So we no longer join anything, just find the latest pipeline
and load builds from there to avoid mixing builds.

Thanks Kamil for the help and tests.

another_artifacts was no longer used and then there's no point to
put let in outer scope anymore.

this should properly test that it's really getting the
builds from the latest successful pipelines and latest
successful builds.

also added a test for checking this.

rubocop was complaining

Also we give undesired builds another artifacts so that we could tell
if returned artifacts was we actual expected.

Added redirect_to_referer to login link on issues

## What does this MR do?

Adds a `redirect_to_referer` param to login & register links on issues when not logged in. This makes the login box redirect back to the issue after login.

## What are the relevant issue numbers?

Closes #19968 

See merge request !5344

This was extracted from !5142 and implementing part of #4255.
We split it from !5142 because we want to ship it in 8.10
while !5142 was not ready yet.

Add support for manual CI actions

## What does this MR do?
This implements a `when: manual` which allows a jobs to be marked as manual actions.
Manual actions have to be explicitly executed by developers.

## What are the relevant issue numbers?
This is to solve: https://gitlab.com/gitlab-org/gitlab-ce/issues/17010

See merge request !5297
