Fix the "Update Patch" workflow on afor generic Differential revision (like Diff 123)s.
For exampleYou can now help a coworker to update their patch, this happens when you help a coworker to updatefrom their patch web.
So, if you visit Diff 123111 (not yours) and you click "Update Patch"Diff", and you paste a valid diff,
you arrive here:
https://we.phorge.it/differential/diff/9876222/?revisionID=12311
That page as default was suggestsing some Diffs that are yours. Plus, it shouldnow it show the current Diffs Diff 111.
After this change the currentOmitting the Diff is finally available, even if it's not yours, as soon as you can View and Edit thatfrom which the workflow was started made no sense and it's certainly an oversight.
Any follow-up change is welcome to modernize the selector using AphrontFormTokenizerControl.
