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. Bug: Issue 5412 Change-Id: Ia8b2f0abe1d24a3849628fe335c931f07bcaff52
