Remove hardcoded IDs from NetworkGroup objects in net check test
Remove hardcoded IDs from NetworkGroup objects in net check test

The IDs of objects created in test_check_untagged_intersection_failed
are no longer hardcoded. They will instead use the next value of the
ID column sequence. This prevents conflicts between transient and
persistent objects in the SQLalchemy session as they will no longer
have the same identifier.
