[BUG] Correct changed files for codeowners

- Backport of #2507
- The CODEOWNER feature relies on the changed files to determine which
reviewers should be added according to the `CODEOWNER` file.
- The current approach was to 'diff' between the base and head branch,
which seems logical but fail in practice when the pull request is out of
date with the base branch. Therefore it should instead diff between the
head branch and the merge base of the head and base branch, so only the
actual affected files by the pull requests are used, the same approach
is used by the diff of an unmerged pull request.
- Add integration testing (for the feature as well).
- Resolves #2458
