Fix Ctrl+n shortcut in locator widget in some configurations

With Gnome, Qt seems to send shortcut override events to the
CompletionList, and not to the input field, so handle
the shortcut override for Ctrl+N/P there too.
Technically this is the correct thing to do anyhow, since
CompletionList also handles the corresponding key press events.
