Fixes cleaning up HA Neutron objects

This fixes a race condition where the cleanup method is trying to remove
HA networks, while Neutron is also trying to remove the network - after
the HA router is removed.  This only applies to installations where
Neutron L3 HA is enabled (nosdn cases only).

JIRA: FUNCTEST-454
