Cannot delete folder from the repository

Summary

A repository tree contains ghost folders that cannot be deleted.

Steps to reproduce

  1. Create an empty file in the folder (folder/empty)
  2. Delete the file empty
  3. You should still see a folder in the repository file tree. But it must be missing as the folder doesn't contain any files in it.

Example Project

https://gitlab.com/vyaklushin/my-test-project
