Fix disappearing badge in commit image thread edit

What does this MR do?

When the user is editing a comment of an image thread on the commit page, the badge disappears when the user saves the comment.

❌ Before

Initial	After Edit	Refresh

✅ This MR

In this MR, we fix this by forcing a page refresh when the edit comment is saved.

Note 🍄

Yes, this solution is not ideal but as pointed out here:

Given the rarity of this occurrence (commit comments are rare, image comments are even rarer), I'd be ok in finding a very simple fix, even if forcing a reload of the page.

The code is not shared with MR Diffs and these pages are set to be rewritten into Vue anyway, so not worth putting a lot of effort into it.

Testing case

1. Navigate to a commit page that contains an image.
2. Make a comment on the image by clicking on the image and save that comment.
3. Edit that previously said comment.

• the page will refresh and the badge on the avatar remains.
