Register provider listeners not being called after updating to Laravel 6.0

[ethanransdellrarebird]

Issue / Motivation:

Register provider listeners not being called

Expected behavior:

Socialite::driver('azure')->redirect(); should redirect to the provider's login page

Actual behavior:

InvalidArgumentException with message 'Driver [azure] not supported.'

Steps to reproduce the behavior:

• Create a new Laravel project with version 5.8.*
• Install socialiteproviders/microsoft-azure in Composer, app.php, and EventServiceProvider.php
• Change laravel/framework dependency to ^6.0 and run composer update

Proposed solution:

I've been troubleshooting and see that in this case, the AzureExtendSocialite listener is not being triggered. I was able to dispatch the event manually in tinker and get a die dump from AzureExtendSocialite but still could not get a redirect.

I have the same issue with InstagramExtendSocialite listener.

Debugging with Laravel Telescope, SocialiteWasCalled event is dispatched but no listener are triggered (even if found in php artisan event:list).

Maybe an execution order issue.

Same thing here.

Found that firing the SocialiteWasCalled event is not being added to the app's booted callbacks. Working on a PR.
