Issue:
problem with gitlab push
I have a self hosted GitLab 15.6.0-ee and I cannot push any locally created issues.
I am using the pre built 0.8.0 binary for win64

- Bridge configured correctly (I think)
- Pulled issues from project (with some errors)
- Adopted my gitlab user which comes when I pull
- Add a new bug/issue using the WebUI
- git bug ls shows the new bug

```
>git bug bridge push
exported 0 issues with default bridge
```

As mentioned, the git bug bridge pull did not run cleanly:
```

Discussion:
@MichaelMure: @5nord FYI

Looks like that:
- Gitlab released a new version with new kind of event
- the gitlab bridge assign `EventUnknown` to those when they are not recognized (dropping the details of the event) (for example https://github.com/MichaelMure/git-bug/blob/e762290e237f1e62916e17a901d1f819960d3378/bridge/gitlab/event.go#L144)
- the gitlab bridge return an error when such an `EventUnknown` occurs: https://github.com/MichaelMure/git-bug/blob/9b98fc06489353053564b431ac0c0d73a5c55a56/bridge/gitlab/import.go#L332

That last part is problematic as it's quite reasonable for gitlab to add more events. Point number 2 could also be a problem, depending on how we look at it. I suppose we should just ignore the unknown events. Currently it fails the import of that particular issue (it doesn't commit).
@buestad any idea what kind of event that could be, if you look at the issues that fail to import?

As for the push problem it could be related to that first problem but I suspect it's a different one. The CI does work though, so that could be specific to that new gitlab version.




@buestad: I am 99% sure that the unexpected event is related to commit links. (When a commit message has a # and issue number)
![image](https://user-images.githubusercontent.com/18750265/210523448-275f0a81-bfe3-4d90-93a8-88043a193f62.png)

It looks like after switching identity (user adopt) after the first pull there are some mismatch with the UUIDs on the issues? This also happens if I do a commit to the repos and the pull the issues afterwards.

Here is some console output which might be of interest?:
