Tags within Branch/Tag UI panel can display incorrect data

Issue Summary

When viewing the Tags panel, you can sometimes see a tag that is not actually present in the git repository itself but matches the name of the "default branch" setting within the repository in question.

Steps to Reproduce

1. Create a new repository
2. Open Branches/Tags menu in the WebUI
3. Toggle to the "tags" tab

Expected Results

Only the correct branches/tags should ever be present in their respective tabs.

Actual Results

Additional tag is present despite not being present within the git repository.

Workaround

You can confirm the exact tags present in your repository with a "git tag --list" on a local working copy.
