Only register the telescope service provider if its enabled

• resolves #233 - Disable telescope by default

@allella This should resolve the composer issue you saw when telescope is not enabled. I only register the telescope provider if its enabled

@zach2825 this was merged and pulled, but I'm still getting the error on stage.

Would the following in config.app be causing the class to load?

App\Providers\TelescopeServiceProvider::class

[allella]

Sorry, I meant to say config/app.php

I just patched that file on stage, removing the App\Providers\TelescopeServiceProvider::class and that did allow composer to run without an error.
