network: check stored object is euivalent to what we want to remove

Browse Source 
When object A is stored in Manager::rules and B is in ::rules_foreign,
and compare function for the object cannot distinguish them,
then freeing A causes B to be removed from rules_foreign or vice versa.

Hopefully fixes #12731.
