allow non boolean simple conditionals

[mc0918]

Overview

Previously, the SimpleConditional logic only checked for an array key and its value, i.e.

[
  'when' => 'key',
  'equalTo' => 'value',
  'show' => true
]

for formio data like:

[
  'submissionValues' => [
    'key' => 'value'
  ]
]

However, SelectBoxes and Select with the multivalue option enabled format their values differently, leading to SimpleConditional::invoke() always returning false and the components' values being ignored during validations. An example in SOAP is, because the values of these ignored components are not persisted, missing PDF uploads:

This PR expands the SimpleConditional logic to cover these cases, handling the following:

// SelectBoxes tracks each selected option by setting the corresponding key to true
'submissionValues' => [
    'key' => [
        'option1' => true,
        'option2' => false,
    ],
],

and

// multivalue Select components track each selected option via an array of selected option keys
'submissionValues' => [
    'key' => [
        'option1', 'option2'
    ],
],

So now all the conditionals shown below just work(tm), and values will be persisted.
