    sessionMode: Allow extensions at the login and unlock screens
    
    Now extensions can specify which session modes they work in,
    but specifying the login screen or unlock screen session modes in
    an extensions metadata still won't work, because those session
    modes disallow extensions.
    
    This commit fixes that.
