altTab: fix destroy-without-showing case

Browse Source 
If the switcher is destroyed without ever being fully shown (either
because it couldn't get a keyboard grab, or just because there are no
apps to display), destroy it immediately rather than tweening it
towards destruction, since its contents haven't been built yet and
_allocate() will throw errors if it runs.
