(The below is how I understand this. I am no gerrit expert, though, and I might be
wrong.)
Note this part:
! [remote rejected] HEAD ->
refs/publish/master/mwalker_test (change 59546
closed)
That's gerrit ("remote") telling you that the change is no good
("rejected"), because
https://gerrit.wikimedia.org/r/#/c/59546/ ("change
59546") is already merged ("closed").
This means that instead of submitting the change to whatever branch you wanted to,
you're actually submitting it to master.
You should either fix the .gitreview file to have something else than
"defaultbranch=master" in it for your branch, or just use the good old `git push
gerrit HEAD:refs/for/<branch>` command instead of `git review`.
(Or, if you did mean to submit this to master for some reason, remove the Change-Id line
and have a new one generated to create a new gerrit changeset.)
