Subject: [PATCH 102/127] fix issue #457

I found out I did not set a value for invert when adding the rich rule via firewall-cmd. Then I got the error as mentioned in issue #457 because the invert attribute was given a default value None. I corrected it here so that it gets the default value False. This fixed the issue for me.
