Added logic to identify and remove internal transfers from Affordability snapshot
Accounts object now returns the latest connection.id via the connection attribute. The most recent connection id that was used to retrieve or refresh data - for each account is always returned in the response.
Explanation relating to above change: Since introducing the ability to ingest financial data by multiple means (pdf and csv upload) there is no longer a concept a clean 1:M mapping between connections and accounts. This meant that the relationship between connections and accounts changed entirely. Links to connections on both accounts and transactions endpoint will return null from here forward and the attribute will be removed in the next version of the API.
