Highlighter: fix crash after closing file

Browse Source 
Regular expression rules are tracked inside the progress data to inform
the rule about a finished highlighting process. A cloned rule was not properly
tracked. That results in a rule that tries to untrack itself on
destruction after the progress data has already been deleted.
