Deleting a tag using the Web UI generates a duplicate entry on the activity log

Summary

Deleting a tag from a repository using GitLab Web UI (not using git CLI) results in two exact same entries on the activity log for the user.

Note: Using git push origin :refs/tags/<tag> in order to remove the tag, only one activity log entry is generated.

Steps to reproduce

1. Go to a test project repository with one or more tags.
2. Choose to delete one of these tags.
3. Check your user activity at https://gitlab.com/dashboard/activity

Example Project

A new clone of GitLab CE is sufficient.

What is the current bug behavior?

Duplicate entries about the tag deletion are added to the activity log.

What is the expected correct behavior?

Only one entry should be added to the activity log.
