[Benjamin Berg <bberg src gnome org>]

commit 05ea8ef5a0b31ce55a28d62effe4305f0ac9b115

    power: Drop lid switch inhibitor when session is inactive
    
    We should never hold on to inhibitors when our session becomes inactive.
    Implement the appropriate logic for the lid switch, going through the
    same delay logic as for normal monitor events.
    
    Fixes: #504
