Updates spec setup for StagePresenter and Ci::Build - 5/10

What does this MR do and why?

As we are trying to remove the build.stage column, a lot of spec setup need to be updated in order for this to happen.

From:
create(:ci_build) { (stage: 'name' ...

to

create(:ci_build) { (stage_id: stage.id ... OR create(:ci_build) { (ci_stage: stage...

This is MR 5/10
