What Operating System are you using (both controller, and any agents involved in the problem)?

Windows (should not matter)

Reproduction steps

1. Create an Organization Folder job Job that make use of the plugin, with the checkout credentials Key.
2. Set the project owner to a subgroup, named foo/bar
3. A gitlab project under foo/bar named P
4. P have an open MR created from a fork someone/P that is a private fork, which gives no access to the checkout credentials Key.
5. Run the Scan Gitlab Group

Expected Results

During the scanning process of foo/bar/P, the MR is found. The plugin found that it cannot clone the merge-head revision. Thus just ignore this MR, and continue to scan the leaving things.

Actual Results

The entire Scan Gitlab Group failed,
