Running URI through UriNormalize Filter appends `/` - causes Hostname TLD check to always fail

[rkeet]

If you run any hostname through UriNormalize, at some point the normalize function in the Uri module is run. This module calls normalizePath function.

This function appends a / to the end of the URI.

Next, when you try to validate the URI with Hostname validator with 'useTldCheck' => true, in the options, it will always fail.

Steps to reproduce

Have the following in a fieldset

        $this->add(
            [
                'name'       => 'someUrl',
                'required'   => true,
                'type'       => Text::class,
                'options'    => [
                    'label' => 'Some URL',
                ],
                'attributes' => [
                    'maxlength' => 100,
                ],
            ]
        );

Have the following in an InputFilter:

        $this->add(
            [
                'name'       => 'someUrl',
                'required'   => true,
                'filters'    => [
                    ['name' => StringTrim::class],
                    ['name' => StripTags::class],
                    [
                        'name'    => ToNull::class,
                        'options' => [
                            'type' => ToNull::TYPE_STRING,
                        ],
                    ],
                    [
                        'name'    => UriNormalize::class,
                        'options' => [
                            'enforcedScheme' => 'https',
                        ],
                    ],
                ],
                'validators' => [
                    [
                        'name'    => StringLength::class,
                        'options' => [
                            'min' => 1,
                            'max' => 100,
                        ],
                    ],
                    [
                        'name'    => Hostname::class,
                        'options' => [
                            'allow'       => Hostname::ALLOW_DNS,
                            // Allow only DNS names
                            'useIdnCheck' => true,
                            // Check IDN domains - International Domain Names - supports international characters in DNS of country TLD, e.g. *.de (Germany) TLD
                            'useTldCheck' => true,
                            // Validates the existence of the TLD itself (the .com part of the domain)
                        ],
                    ],
                    [
                        'name'    => Uri::class,
                        'options' => [
                            'allowRelative' => false,
                        ],
                    ],
                ],
            ]
        );

I've got a few more issues reported that I'm solving, next to projects and a full-time job, I most likely will not have time to fix this. Would appreciate someone stepping in to fix this one. If not I might get around to it after other issues in zend-form and/or zend-inputfilter are finished.

[rkeet]

                    // Remove trailing '/' char from tld string if present
                    if (substr($this->tld, -1) === '/') {
                        $this->tld = substr($this->tld, 0, -1);
                    }

I would suggest this after line 2052 in Hostname.php file.
