After pushing a S/MIME signed commits using [smimesign](https://github.com/github/smimesign) to GitLab, the UI shows `An error occurred while loading commit signatures` on top of the page. Also, verification badge pinwheel next to commit hash keeps spinning forever, for every commit in the commit history. Ideally, GitLab should be able to verify the S/MIME signed commit (or) at the least, show `unsupported signature`. To reproduce the issue 1. Setup git to use smimesign utility 2. Make a commit with `-S` option 3. Push code upsteam 4. Open the URL for the repository Example GitLab repo https://gitlab.com/ven/smime_test/commits/master
