Verifies collection is correct type and calls connect on providers.

Note: This is the same code as {@see Silex\Application::mount}

@param ControllerProviderInterface|ControllerCollection $collection

@throws LogicException If controllers is not an instance of ControllerProviderInterface or ControllerCollection

@return ControllerCollection
Verifies collection is correct type and calls connect on providers .
