Commit's Roots cache stores block_timestamps for the CommitReports, but
when reorgs happens block_timestamp can also change because TX could be
included in a different block.

Example scenario:

CommitRoot with 10:30:00 UTC block timestamp is inserted with
`AppendUnexecutedRoot` (so it's block_timestamp is persisted in the
cache). Then reorg happens on the destination and the same CommitRoot is
inserted into the blockchain but let's say with 10:29:00 UTC (different
block_time), which is never updated. Commit Roots cache returns
persisted 10:30:00 as the oldest block timestamp and we keep searching
LogPoller using the wrong lower bound filter - this Commit Root never
pops up in the execution because it's never returned from DB
