NetDB: RI Publish improvements part 1

Speed up initial publish

After reading in 500 RIs,
PersistentDataStore.ReadJob calls setNetDbReady() which calls publish(),
but that fails because netdb.isInitialized() returns false
until PersistentDataStore finishes reading in all the RIs.

Fix isInitialized() so it will return true before we call setNetDbReady().
Also add a missing check to make sure we don't call setNetDbReady() twice.
and a check in setNetDbReady() so we don't call publish() twice.
