When we encounter a truncated CSV get a new stateful query session

[cosimon]

Description of change

When we encounter a truncated CSV get a new stateful query session.

The Zuora API can sometimes send us a non-rectangular CSV file (ie the number if items in a row is less than the number of columns). Testing has shown that when this happens in a stateful AQuA session then that session will from then on continuously return non-rectangular CSV.

This tap uses the version bookmark as part of the key for the AQuA query session. By generating a new version bookmark the tap ensures that on the next sync after encountering the non-rectangular CSV it will get a new query session.

Manual QA steps

• Ran this on a connection that was receiving this non-rectangular exception. Running on this branch the tap encountered the exception once and fixed its state. On the subsequent run it was able to complete the sync.
