Revert "Disable replication when writing to the pending bootstrap store"

[tgoyne]

This reverts commit afe0e0f.

DisableReplication actually disables replication on the DB, not the Transaction, so it's extremely unsafe to use. This was a very minor optimization so it's not worth doing if there's anything complicated about it.
