Migrate pipelines graph folder spec to jest
What does this MR do?
Move the pipelines karma specs from the graph folder to jest. See #194249 (closed) for reference, though i am not moving everything listed in there, just the graph folder for now.
Screenshots
Nothing since it's only tests migration
Notes
Because I moved the mock data, the MR says that it's too big but really it's just a big file that was moved. I think the mockData files can safely be ignored in the reviews.
