[GITEA] API commentAssignment() to verify the id belongs

Browse source 
Instead of repeating the tests that verify the ID of a comment
is related to the repository of the API endpoint, add the middleware
function commentAssignment() to assign ctx.Comment if the ID of the
comment is verified to be related to the repository.

There already are integration tests for cases of potential unrelated
comment IDs that cover some of the modified endpoints which covers the
commentAssignment() function logic.

* TestAPICommentReactions - GetIssueCommentReactions
* TestAPICommentReactions - PostIssueCommentReaction
* TestAPICommentReactions - DeleteIssueCommentReaction
* TestAPIEditComment - EditIssueComment
* TestAPIDeleteComment - DeleteIssueComment
* TestAPIGetCommentAttachment - GetIssueCommentAttachment

The other modified endpoints do not have tests to verify cases of
potential unrelated comment IDs. They no longer need to because they
no longer implement the logic to enforce this. They however all have
integration tests that verify the commentAssignment() they now rely on
does not introduce a regression.

* TestAPIGetComment - GetIssueComment
* TestAPIListCommentAttachments - ListIssueCommentAttachments
* TestAPICreateCommentAttachment - CreateIssueCommentAttachment
* TestAPIEditCommentAttachment - EditIssueCommentAttachment
* TestAPIDeleteCommentAttachment - DeleteIssueCommentAttachment
