Update GateCollector (barryvdh#735)

addCheck assumed that the authorized model was the authenticated App\User. In my case I have a App\User, App\Account and an App\AccountUser. The App\User is authenticated but authorizations are on the App\AccountUser which does not implement Authenticatable.

This change type hints $user to Authorizable because thats what is really important in this collector. It also uses the Authorizable's base class name in the message instead of assuming user.
