Service provider auto discovery support not working

[chosten]

The service provider auto discovery is not registering the proper provider.
It registers the TmdbServiceProviderLaravel5 provider instead of TmdbServiceProvider.
This prevent the API from working because the Tmdb\Client singleton is not setup.

Registering the provider manually fix the problem.

@squarebeard Thank you for the report and the steps to fix the issue. I think the auto discovery should work correctly after applying #55.

@laravelish Don't despair! ;) Pull-requests are still welcome and we will do our best to review them.
