[ABW]: added .orig and .pat for calls that result in no result (we need to add some message)

fixed key order in two bridge_api tests
null_result no longer used (we always need either empty results or error message where applicable)
added comments to new bridge_api tests, properly marked which pass and which fail (and why)
accepted differences in new test patterns: rebranding, reputation, pending payouts, future payout_at, post_id
