Doesn't find Inspector class when Facade is not registered

[arubacao]

I'm only using this library during development.
In my AppServiceProvider ich first check if i'm in development ($this->app->environment() == 'development') and then register the service provider for the inspector.

However, i'm not registering the facade and this error pops up:

I feel, that this the inspector should also work with no facade in the base namespace.
I'm preparing a PR to fix it, feel free to merge if you want to.
Thanks, for the great library.

Cheers
