    selectionbar: Don't let user delete under-construction VMs
    
    While the ideal solution is probably to make it possible for user to
    delete under construciton VMs too, it would be pretty difficult to
    implement with us launching external processes as part of such
    construction. Keeping in mind also that this only affects imported (from
    installed media) VMs and importing usually takes much less time than
    installations, I think this is not bad at least as a temporary work
    around.
