Make revision generation deterministic
This removes the influence of the attachment disk information when
generating revisions when a document is being recreated (ie, it existed
once but has been deleted).
Big thanks to @tonysun83 for getting a reproducer as well as the test
included with this PR.

> When a document is re-created with an attachment it receives a
> non-deterministic revision. This is due to a fairly old commit [1] that
> introduced the behavior by accidentally including information about revisions
> on disk into the revision id calculation when the revision id was being
> calculated by couch_db_updater when it realized that the update was
> re-creating a document that was previously deleted.
> I'm opening a PR with the fix.
