Merge branch '23662-issue-move-user-reference-exception' into 'master'

Fix `User#to_reference` ## What does this MR do? Fix the method signature of `User#to_reference` so that moving an issue with a user reference does not throw a "invalid number of arguments" exception. ## Why was this MR needed? 1. Changes in 8.13 require `Referable`s that don't have a project reference to accept two arguments - `from_project` and `target_project`. 2. `User#to_reference` was not changed to accept the `target_project` (even though it is not used). Moving an issue containing a user reference would throw a "invalid number of arguments" exception. 3. The regression was introduced in [c8b2b3f7](https://gitlab.com/gitlab-org/gitlab-ce/commit/c8b2b3f7c32db873f1bebce3e3b1847ea24d235f#91fabb7ad88bd2fde6fef1c100a719c00e503047_75_79), which expects all `Referable`s that don't respond to `:project` to have a `to_reference` method that takes two arguments. ## Does this MR meet the acceptance criteria? - Tests - [x] Added for this feature/bug - [ ] All builds are passing - [x] Conform by the [merge request performance guides](http://docs.gitlab.com/ce/development/merge_request_performance_guidelines.html) - [x] Conform by the [style guides](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/CONTRIBUTING.md#style-guides) - [x] Branch has no merge conflicts with `master` (if it does - rebase it please) - [x] [Squashed related commits together](https://git-scm.com/book/en/Git-Tools-Rewriting-History#Squashing-Commits) ## What are the relevant issue numbers? - Closes #23662 See merge request !7088
