histedit: don't swallow errors that happen when updating the working copy

Commit 34165875fa5d (histedit: limit updated and merging output to
important updates, 2016-02-03) added a call to
`ui.pushbuffer(labeled=True, errors=True)`. I don't know if there was
a reason for the `errors=True` (nor the `labeled=True` bit, which I
removed in the previous commit). It seems bad to just discard the
errors, so let's not do that. By not doing that, we can also remove a
workaround for the lack of errors from `test-removeemptydirs.t`.
