Updated rails patch

Generate system note after Task item has been updated on Issue or Merge Request.

Reference: #2296 

Everytime the User check or uncheck a Task Item from the Issue or
Merge Request description, a new update is going to be
added to the activity logs of the Issue or Merge Request.

Note that when using the edit form, you can only update the Task item
status or add/delete/modify existing ones. Doing both actions is not
fully supported.

Handle removed source projects in MR CI commits

Fixes #3599 

@dzaporozhets assigning this to you since you wrote the original code. Perhaps checking for the source project isn't the right way, but I'm not sure if there's a better way (e.g. somewhere earlier in the process) that we can detect this.

Add upvote/downvote fields to merge request and note API to preserve compatibility

As discussed in !1825 we should not break the API compatibility.

* This MR adds the fields `upvotes`/`downvotes` to the merge request API again, which always return `0`.
* Add the fields `upvote`/`downvote` to the notes API, which always return `false`

This behavior is documented in the API docs.

Make tag API for release feature consistent

Make tags API consistent with other tags methods. This changes the endpoint from `PUT /projects/:id/repository/:tag/release` to `PUT /projects/:id/repository/tags/:tag_name/release`.

On thing the API is still missing, is an error if the tag does not exist. Right now it returns 200 even the tag does not exist. I'll fix that such it returns 404.

@stanhu Can you review?
@rspeicher This MR should go into 8.2
