Becky Siegel 6cd5590a15 Fix local storage with PARENT revision
Previously, if a PARENT revision was getting compared to a patchset,
the local storage key would be the same for both, and there were issues
if a user was trying to write drafts on the same line on either side.

This addresses the issue by storing 'PARENT' as the patch number in the
local storage key, so that each key is unique.
