If we fetch block_retention parent blocks while trying to reconcile a new head and we still haven't lined up the chains then throw an exception rather than rolling back old chain and applying a new one. This is an exceptional state that the user needs to deal with (or crash the app).
Note: Verify this isn't already current behavior first.
