Collision check cache metadata is not updated

[splushii]

If a rule is moved from one file to another or changes description the cache entry will not be updated because the cache entries are only keyed by fsm_cache_key = domain + str(match_tree). We have two alternatives:

• Key by all metadata values used in the cache entries (domain, match_tree, file path and description)
• Update cache entry metadata (file path, description)

The first solution is a bit simpler, but the second one is more performant (because then we don't need to calculate a new FSM every time the rule changes file / description / other metadata)

To reproduce:

1. Run ORM with collision checking and caching
2. Move a rule from one file to another
3. Invoke a collision with the moved rule
4. Run ORM with collision checking and caching (and see the faulty metadata in the output)
