Follow-up from "Fill default suggestion commit message values in the placeholder instead of showing the variable slugs"
The following discussion from !52851 should be addressed:
- [ ] @thomasrandolph started a [discussion](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/52851#note_499156188):
> This whole describe is not good!

> Unfortunately, the way this test suite is set up uses a lot of old, brittle patterns.
> Updating them to facilitate the mocking necessary here (multiple stores, for example) would result in a lot of changes to this file unrelated to this MR.

> I'm opening a follow-up issue to just come back here and update this whole file to use testing patterns more in line with our standards.
tl;dr: The file uses old testing patterns, and should be updated to fully use more standard stuff (`@vue/test-utils`, etc.)
