This is somewhat of an uncommon case where if a plugin fails to merge a user, the merge would fail but the
user_email
of thesource_user
would have been transferred to thetarget_user
. This leaves thesource_user
without an email, and this bug would occur when admins try to access/admin/users/<id>/<username>
.This allows the admin to continue dealing with the user.

A consideration here would be to use a transaction (probably very costly), or reorder the order of events in
UserMerger.merge!
