macOS: Simplify reflection delegate handling in QCocoaApplicationDelegate

Sending a message to a nil object returns nil, so there's no reason to
check the delegate before calling respondsToSelector, and we can use
the implicit _cmd argument to pass along the selector for the method
we're in.

For applicationShouldTerminate, if there's a reflection delegate but
it doesn't answer to applicationShouldTerminate it makes no sense to
skip our own logic.
