Update Debugbar to include autoshow setting (#1393)

I think that's a valid point to include, due to the fact that in a lot of software with the autoshow set to true it's impossible to use the debugbar.
I'm in Laravel Nova right now, every time a notification ajax gets sent, the request I'm debugging gets removed by that setting.
I've tried to add a middleware to enable that setting, but it breaks other things in beetween.
Right now this it's the most polished solution.
Let me know if it's ok!
Thanks!
