Title: More resurrected HA tests that were temporarily removed for HA 1.5.

Fixes issues that these new tests discovered:
o The cached contents in the IndexStore instance could become stale after
copying a new store from the master. Solved by invalidating.
o Index locks (IndexLock) were silently ignored in the HA scenario,
which made Index#putIfAbsent not atomic.
