    viewSelector: Don't show the workspacesDisplay actor when starting up
    
    We're always starting up to the APPS page, and making the workspacesDisplay
    visible when starting up would cause its actor to intercept Clutter 'picks'
    intended for the grid unless it gets hidden first.
    
    Since we're not interested in showing the Window picker on start up, just
    avoid showing the workspacesDisplay actor when starting up to prevent this.
