Since we are going to handle the API stuff later we can just leave this as error case since the model validations will stop this

Per discussion in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/9646#note_65730532 this logic is being optimized elsewhere and it will simplify things if we make less changes to this code right now.

Rename `runner.belonging_to_group(project.id) -> runner.belonging_to_parent_group_of_project(project.id)`

Closes #44177

See merge request gitlab-org/gitlab-ce!18407

Direct disk access is done through Gitaly now, so the legacy path was
deprecated. This path was used in Gitlab::Shell however. This required
the refactoring in this commit.

Added is the removal of direct path access on the project model, as that
lookup wasn't needed anymore is most cases.
