Merge branch 'fix-mr-for-orphaned-branches' into 'master'

Fix creation of merge requests for orphaned branches with images

When attempting to create a merge request from an orphaned branch (e.g. this happens for the first commit of any repo) that contained images, GitLab would fail with a Error 500. This MR fixes that problem.

Closes #14875
