Don't call Application::Quit() in Desktop::terminate() on iOS

When exiting from a document in the iOS app, the Application::Quit()
would post an ImplQuitMsg user event that would however not be handled
for that document. Instead, it would be handled by the next document
opened and thus the code would immediately stop editing the document,
causing grief.
