Fix "unmarked 0 inline comments as not undone" transactions

Summary:
Fixes T8483. I did this incorrectly in D13159, by doing it correctly first and then editing it carelessly. For most transaction types, it didn't matter, but did for inline state.

Also, clean up any bad inline state transactions.

Test Plan:
  - Ran migration, bad transactions vanished.
  - Marked some inline comments as done.
