Remove all application callers to "putInSet()"
Summary: Ref T13218. This is the last public-facing API call for loadRelatives/loadOneRelative. This just "primed" objects to make the other calls work and had no direct effects.
Test Plan:
- Ran bin/fact analyze.
- Used bin/storage upgrade -f --apply to apply 20181031.board.01.queryreset.php, which uses LiskMigrationIterator.
- Browsed user list.
