Drop the spec in YamlProcessor that reads current .gitlab-ci.yml

See merge request gitlab-org/gitlab-ce!20240

Prior to this change, most the commits counted were done through Gitaly.
This removes the last point where this wasn't the case.

This makes the `rugged_count_commits` method obsolete, with its tests.

Closes https://gitlab.com/gitlab-org/gitaly/issues/315

Drop the spec in YamlProcessor that reads current .gitlab-ci.yaml. If the .yaml file is not valid, specs would not run in CI.
