Remove application callsites to "LiskDAO->loadOneRelative()"

Summary: Ref T13218. This is like `loadOneWhere(...)` but with more dark magic. Get rid of it.

Test Plan:
- Forced `20130219.commitsummarymig.php` to hit this code and ran it with `bin/storage upgrade --force --apply ...`.
- Ran `20130409.commitdrev.php` with `bin/storage upgrade --force --apply ...`.
- Called `user.search` to indirectly get primary email information.
- Did not test Releeph at all.
