shell-app: Unref running state when window count drops to zero

Browse Source 
With the lastest ShellApp changes, an app is considered stopped
when the last "interesting" window is closed. However the app
may still track non-interesting windows, so if we unref the
running state on the state transition, we hit an assertion later-on
when trying to remove the non-interesting window.
Fix this by keeping the running state around until the last window
is closed.
