Add end-to-end test for creating and editing issue comments
What does this MR do?
Increase the end-to-end test coverage to avoid regression in the functionality of editing an issue comment.
This functionality was broken for a while, and this MR intends to allow us having quick feedback about it before we deploy the broken feature in production.
Does this MR meet the acceptance criteria?
