[fixing] - Remove path Token in Lcobucci\JWT\Builder for Laravel 5.7

[deyan-ardi]

An error in methods getBuilderFromClaims, Return value of Tymon\JWTAuth\Providers\JWT\Lcobucci::getBuilderFromClaims() must be an instance of Lcobucci\JWT\Token\Builder, instance of Lcobucci\JWT\Builder returned

So i deleted Token path, from use Lcobucci\JWT\Token\Builder; to use Lcobucci\JWT\Builder; for fixing this error
