autoWorkspaces: Better handle apps that open a splashscreen or dialog at startup

Browse Source 
Currently we remove a workspace when last window on that workspace closes,
which turned out to be too agressive as some apps open either a splashscreen
or a "I have crashed last time" dialog at startup.

Try to detect such apps and give them a chance to open their "real window(s)"
on the workspace.
