Fix broken tests, right now I'm manually writing the docs after each
api_call, before this 2f64dfe78d65d25b9670456ee6e759b66979c762 an
api_call did a docs writing operation.

2f64dfe78d65d25b9670456ee6e759b66979c762 meant that you have to manually
decide when to write the documents.

Also removed the setup hooks on test_helper_test because it is useless if
you instead use rspec.
