Revamped RuleViolationsManager and FlowAnalyzer handling to make sure no issue occurs when these are not set. Fix ResourceNotFoundException: When determining the subject permissions for a rule violation the type of the subject is now known, so we try to lookup all possible types. Non-matching tpyes throw a ResourceNotFoundException exception though. Going to ignore those.
This closes#7809
