Merge branch 'fix/deleted_file' into 'master'

Fix deleted file representation with new gitlab_git gem

Added this MR as per request from https://github.com/gitlabhq/gitlabhq/pull/7980

* Add new gitlab_gem as per gitlab-org/gitlab_git!6
* Fix the showing of deleted file, as it only displays the named of the file, rather than specifying what had happened
