Becky Siegel a88f8c82d4 Fix corner case where storage gets duplicated for patchsets
Previously, there was an issue where if you create a draft comment in
side by side view and switch to unified view, the comment thinks it's in
the later patch set rather than the earlier one and a second copy gets
added to local storage with the later patchset as a component of the
key.

This was because the the thread group assumed all threads inside of it
had the same patch number. This change fixes that, so in the event that
a user switches from side by side to unified, the patch number will get
taken from the comment rather than the thread group.

Bug: Issue 5493
