Changes / Features implemented
Optimise CSV export process. Avoid traversing data to build CSV columns for repeat responses. Instead use a register that has a record of how many columns we should have for each repeat question.
If the register for a form is unavailable, fall back to building the columns from data and trigger an asynchronous task to create the register
Fixed flaky test
