Minor release

• Add Laravel 5.5 service provider auto discovery support (#33, #35)

With this release we've made php-tmdb/laravel compatible with version 3 of Symfony's event-dispatcher while still supporting version 2.8.
The EventDispatcherAdapter has been simplified, it now directly calls symfon's (and Laravel's) event-dispatcher.
The tests have been rewritten such that we no longer depend on the tests files from symfony/event-dispatcher

This is a fix for Laravel version ~5.1.
