Bug Description

Check+Set Race Conditions in RecordSet creation, in the APIv1 Records endpoint, and the Base sink notification handler, we have a check+set race condition.

Specifically, the _find_or_create_recordset methods - if executed simultaneously can fail to do the right thing.

We should reverse the order of this, attempt to create, then if we get a Duplicate, fetch the existing.
