The advantage of this is that tests are less about logic and more
straightforward, thus could be easier to reason about each individual
tests.

The disadvantage of this is that we write more duplicated codes and
once something changed we might need to change all places and it's
harder to reason all tests as a whole. Because now we need to look at
more places to figure out how it should work under another option!

This also moves tests from build_spec.rb to runner_spec.rb

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/4093#note_12321029

Without that, Rails would complain:

> bind message supplies 5 parameters, but prepared statement "a4" requires 4

However without this workaround it would still work in Rails console,
so I still think this is a Rails bug somewhere.

Also add a test for setting locked.
