Tests: test irccdctl (rule-* commands) #785 While here, fix rule-edit which were triggering invalid_index because it was not added to the request. Also fix missing events from configuration file because they were forgotten. Finally, use std::set instead of std::unordered_set for a sorted output in rule-list and rule-info to ensure long-term compatibility in output.
