Subject: Query by `Id` rather than `ProbeFreezeId`

Previously `ProbeFreezeId` was set as 1 more than the largest `Id`
value found, which might not end up being the same as the incremented
Id.
This commit, thus, queries by `Id` which is more robust, and does an
actual update for the `ProbeFreezeId` column to make it same value as
`Id`.
