index: Use first block from locator instead of looking for fork point

Browse Source 
The index sync code has logic to go back the chain to the forking point, while
also updating index-specific state, which is necessary to prevent
possible corruption of the coinstatsindex.

Also add a test for this (a reorg happens while the index is deactivated)
that would not pass before this change.
