Fix pipeline error when trying to read empty merge request diff
When a user pushed something which resulted an empty merge request diff, `st_commits` would be `nil`. Therefore we also need to check if there exists `st_commits`.
We could tell this from:
``` ruby
def commits
@commits ||= load_commits(st_commits || [])
end
```
and
``` ruby
def save_commits
new_attributes = {}
commits = compare.commits
if commits.present?
commits = Commit.decorate(commits, merge_request.source_project).reverse
new_attributes[:st_commits] = dump_commits(commits)
end
update_columns_serialized(new_attributes)
end
```
Closes #22438
