Fix rbt patch when applying patches from users with private profiles.
Review Request #10314 — Created Nov. 8, 2018 and submitted — Latest diff uploaded
If a user has marked their profile private, their full name and e-mail
address will be stripped from the API payloads. This would cause
rbt patch -c/-Cto fail with an AttributeError when attempting to
create the commit.
This change fixes it so we create the commit as the running user.
Applied a patch from a user who had marked their profile private.
