Bug Report: If VTOrc is configured to convert tablets with errant gtids to drained type, it soon forgets them

[GuptaManan100]

Overview of the Issue

It was noticed that if VTOrc is running with the --change-tablets-with-errant-gtid-to-drained flag, then after it converts a tablet that has an errant GTID to a drained type, it forgets them! This leads to the metric of ErrantGTIDTabletCount to be incorrect, since VTOrc removed the tablet that had the errant GTID from its list of tablets! That metric then always reports a value of 0 which is incorrect since we have errant GTIDs that need to be looked at by the user.

Reproduction Steps

1. Run VTOrc with --change-tablets-with-errant-gtid-to-drained flag
2. Introduce an errant GTID on a replica.
3. Monitor the ErrantGTIDTabletCount gauge and see that it goes to 0 even without us fixing any errant GTID.
