shell/window-tracker: Track windows getting unmanaged

Browse Source 
It makes sense to not rely on workspaces' ::window-removed
signal, and we already do that in ShellApp.

However it is odd to remove a tracked window from the app,
but still track it in the window tracker. Move the code
to remove unmanaged windows from both.
