Gerrit won't permit more than one commit using the same change
number during a replacement request, so we should error out if
the user has asked for this in their upload edit script.

Users are prompted with the list of known changes we are about
to upload, and they can fill out the current change numbers for
any changes which already exist in the data store. For each of
those changes the change number and commit id is sent as part of
the upload request, so Gerrit can insert the new commit as a new
patch set of the existing change, rather than make a new change.
This facility permits developers to replace a patch so they can
address comments made on a prior version of the same change.

This way users are well aware of which account we used when the
uploads are complete, so they can be certain to sign into the web
application with that user identity.
