    power: Fix possible assertion on startup
    
    When opening the Power panel, and if power-profiles-daemon isn't already
    started, we'll be autostarting it, making it send signals about all the
    changed properties, including "PerformanceInhibited" even if we
    don't have a Performance row.
    
    Ignore the property change if we don't have a row for it rather than
    asserting.
