Full sync bookmark is set as null if there is no new responses in run #38
Description
When running a tap for responses stream and there happens to be 0 new responses, the sync sets full_sync bookmark as null, triggering a full sync on the responses stream in the next run. It should preserve the current state to avoid unnecessary full syncs that easily clog up SurveyMonkey's API quota.
