Description of problem: I create 2 acls that will be identical in nbdb, only have different names, then I see these 2 acls will get translated to only 1 set of logical flows in sbdb, and will have one of the ACL uuids in stage-hint. Then if I delete that ACL that is listed in stage-hint, sbdb logical flows will stay the same (which is expected, since there is 1 equivalent ACL left), but stage-hint will stay the same, with UUID of ACL that doesn't exist anymore. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Create 2 equivalent ACLs with different names in nbdb 2. Check only 1 set (that is 2 flows for "reg0[10] == 1" and "reg0[9] == 1") of logical_flows created, find nbdb ACL UUID in stage-hint 3. Delete ACLs with UUID noted in the previous step 4. Check logical_flows are the same, including stage-hint of non-existing ACL
