Version 1.0 adds EVERYWHERE some "N" letter at the top of the screen and won't disappear even after removal

Your environment

Q	A

Steps to reproduce

composer require tymon/jwt-auth:dev-develop --prefer-source php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider" php artisan jwt:secret

"N" letter should not appear and SHOULD NOT STAY after removal.

Removing, renaming jwt.php seems to do the trick.
