Can't unclaim post after cancelling from 'Revise post'

[Banson]

@pento

Any automatically claimed reviewable should be automatically unclaimed when you either finish moderating the reviewable, or cancel out of process.

Thanks @pento for explaining. Previously the automatically-claimed topic stays claimed even when I resolve all its current reviewble items, so all its future flags can only be responded by me, which is annoying. Should I expect the PR fix this?
