    unlockDialog: ignore resets after success
    
    GDM sends a reset signal after verification succeeds
    so that a user-switched login screen can prepare for
    the next time it's going to be used.
    
    The unlock screen treats resets as failures, though.
    This means, on success, we're emitting "failed" and
    clearing any last second messages.
    
    This commit changes the unlock code to ignore resets from
    GDM after successful verification.
