[Patch] created_by is not changed when reverting multiple changesets

[GerdP]

What steps will reproduce the problem?

1. Revert multiple changesets
2. Click upload
3. Click continue upload if validator complains
4. Click tab "Tags of the new changeset", note that created_by doesn't mention reverter
5. Cancel the upload

What is the expected result?

Like with a revert of a single cs the created_by tag in the new changeset should contain reverter
(or maybe better reverter/<version>, see #12400)

What happens instead?

created_by doesn't contain "reverter"

Please provide any additional information below. Attach a screenshot if possible.

The attached patch fixes this problem and partly reverts #12400 to add the plugin version again.
