Additional fix to handle NULL lock_versionsh-fix-activerecord-patch-mark2
If the UI sends a string value for lock_version (e.g. "0"), then the previous monkey patch did not properly handle that properly. This commit casts the value to an integer to determine whether to look for NULL lock_versions. For merge requests, GitLab sends a POST request to `namespace/project/merge_requests/:iid` with the `merge_request[lock_version]` parameter with a string `0`. The string value comes from the form field, which explains why https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/28145 wasn't sufficient.
