Hotfix: PHP 7.4 compatibility

[waahhhh]

Provide a narrative description of what you are trying to accomplish:

• Noticed deprecated messages on PHP 7.4:

  [10-Dec-2019 04:18:49 UTC] PHP Deprecated:  Function ReflectionType::__toString() is deprecated in /var/www/html/vendor/zendframework/zend-di/src/Definition/Reflection/Parameter.php on line 65
  [10-Dec-2019 04:18:49 UTC] PHP Stack trace:
  [10-Dec-2019 04:18:49 UTC] PHP   1. {main}() /var/www/html/bin/di-generate-aot.php:0
  [10-Dec-2019 04:18:49 UTC] PHP   2. Zend\Di\CodeGenerator\InjectorGenerator->generate() /var/www/html/bin/di-generate-aot.php:22

  [10-Dec-2019 04:18:49 UTC] PHP   6. Zend\Di\Definition\Reflection\Parameter->getType() /var/www/html/vendor/zendframework/zend-di/src/Resolver/DependencyResolver.php:285

• On PHP 7.4 CodeSniffer outputs the messages:

  Deprecated: Array and string offset access syntax with curly braces is deprecated in /var/www/vendor/squizlabs/php_codesniffer/CodeSniffer.php on line 2028
  Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /var/www/vendor/squizlabs/php_codesniffer/CodeSniffer/File.php on line 1766

  But that will be resolved by: https://github.com/zendframework/zend-di/pull/47

@waahhhh Thanks for your contribution.

We can't accept this PR as it is - it contains BC Break (bump PHP version, by us considered as BC Break and can be released only with new major version) and Bugfix for PHP 7.4 compatibility.

Please provide bugfix separately - PR to master, and then other PR with bumped PHP version to develop. Thanks!

[waahhhh]

Removed version bump and changed phpunit/phpunit version from 8.5 to 7.5.

Thanks, @waahhhh!

This PR does not pass static analysis. Why didn't this PR trigger a travis build?

[michalbundyra]

@tux-rampage PR was to master, was merged as a hotfix.
