Removed SeriviceProvider now php artisan won't work

I created my own service provider called TokenAuthServiceProvider.php for a facade called TokenAuth which was for a class called TokenAuth. I had it registered in config\app.php under the providers list, I had an alias registered under `aliases' too. It worked perfectly and I was using it in two controllers and in a middleware. I now don't need it anymore as I wrote something better instead of it. But when I tried to remove it I am getting a fatal error. The steps I took were:

1. Deleted the lines in config\app.php in the providers and aliases lists.
2. Deleted the files
   • TokenAuthServiceProvider.php
   • facades\TokenAuth.php
   • TokenAuth.php
3. Deleted every reference to TokenAuth I could find in all my files (controllers and middleware).
4. Ran in command line $ composer dump-autoload

Now when I run php artisan I get a Fatal Error

vagrant@homestead:~/projects/letsdb/v1$ php artisan
PHP Fatal error:  Class 'App\Letsdb\Providers\TokenAuthServiceProvider' not found in /home/vagrant/projects/letsdb/v1/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146

I don't know how to continue with out the service provider.
