    gui: set fallback VCS if no VCS was loaded
    
    The recursive GFileMonitor only get setup after we discover the VCS
    working-directory. If no VCS was discovered, we never get the workdir
    to set that up.
    
    This checks, after loading a project, if we discovered a VCS and ensures
    we have the fallback VCS if needed.
    
    Fixes #896
