Clear cache in ZeroconfServiceTypes tests to ensure responses can be mcast before the timeout (#634)
- We prevent the same record from being multicast within 1s because of RFC6762 sec 14. Since these test timeout after 0.5s, the answers they are looking for many be suppressed. Since a legitimate querier will retry again later, we need to clear the cache to simulate that the record has not been multicast recently
