Duplicate project entries for GitLab
Duplicate project entries with `.git` suffix. No events are related to the duplicate rows, I suspect handling of the first processed event from the repo, only stage is affected. Going to remove those duplicates and will check here and there, since I cannot see any sources it may be just result of already fixed bug.

```json
[
  {
    "namespace": "lachmanfrantisek",
    "repo_name": "kernel-ark",
    "project_url": "https://gitlab.com/lachmanfrantisek/kernel-ark",
    "prs_handled": 1,
    "branches_handled": 0,
    "releases_handled": 0,
    "issues_handled": 0
  },
  {
    "namespace": "lachmanfrantisek",
    "repo_name": "kernel-ark",
    "project_url": "https://gitlab.com/lachmanfrantisek/kernel-ark.git",
    "prs_handled": 0,
    "branches_handled": 0,
    "releases_handled": 0,
    "issues_handled": 0
  },
]
```

Keeping issue open to not forget about it.

_Edit 1_: two rows on prod too
```
packit=# select * from git_projects where project_url like '%.git';
  id  |    namespace     | repo_name  | https_url |                    project_url                     | instance_url
