Merge errors are logical failures, not technical, it doesn't make sense to log them out because there's nothing to be done technically, a PR having consistency issues or a conflict is "normal". As such those messages are completely useless and just take unnecessary space in the logs, making their use more difficult. Instead of sending them to logging, log staging attempts to the PR itself, and only do normal logging of the operation as an indicative item. And remove a bunch of `expect_log_errors` which don't stand anymore. While at it, fix a missed issue in forward porting: if the `root.head` doesn't exist in the repo its `fetch` will immediately fail before `cat-file` can even run, so the second one is redundant and the first one needs to be handled properly. Do that. And leave checking for *that* specific condition as a logged-out error as it should mean there's something very odd with the repository (how can a pull request have a head we can't fetch?)
