Allow more than 1 action to be registered per automod rule (#2687)

Fixes an issue where you cannot register more than 1 automod rule due to the limit and length of the rules being inverted (This also has the side effect of allowing you to attempt to register 0 actions, resulting in a 50035 invalid body error)
