* record: --user/-u now works with record when ui.username not set (issue3857)

The -u flag didn't work when ui.username was not set and resulted in an
abort message. This was fixed.
* merge: updated the patch to not overwrite config, changed the test

The previous version of the patch relied on overwriting the config to
set the username. That was changed. Also, an error with the test was
fixed and another test was added that explicitly checks the username of
the last commit.
