Mapping parameter should be mixed

[sitole]

Version: 3.0.0-RC3

I upgraded my app to Nette 3.0, but the latest update broke router mapping.

application:
	mapping:
		*: [App, Modules\*, Presenters\*\*Presenter]

For example i want map Frontend:Homepage:Default to App\Modules\Frontend\Presenter\Homepage\HomepagePresenter.php

But new extension schema validator expected only string array (not array of arrays).

application/src/Bridges/ApplicationDI/ApplicationExtension.php

Line 52 in 0f0c24c

'mapping' => Expect::arrayOf('string')->dynamic(),

It should be something like Expect::arrayOf('mixed')->dynamic() or Expect::array()->dynamic().
