Update PhabricatorLiskDAO::chunkSQL() for new %Q semantics

Summary:
Ref T13217. This method is slightly tricky:

  - We can't safely return a string: return an array instead.
  - It no longer makes sense to accept glue. All callers use `', '` as glue anyway, so hard-code that.

Then convert all callsites.

Test Plan: Browsed around, saw fewer "unsafe" errors in error log.
