- we eliminated the storyboard segue in favor of “pushing” either Account Details of the Accounts table, depending on number of accounts present
- we simply pass an `[Account]` to AccountDetails
- updated this change in context to be reflected in Account Table as well
- removed unused boilerplate code in these classes as well

- made changes in AccountDetails and PayBill interface controllers to be more simple, passing only the applicable `Account`
- removed unused boilerplate code

- since we simplified earlier how we pass around accounts, we need to update how we look for the to be sent from Wellness

- for transactions other than processed purchases, `transactionCode` is `NULL` from the server
- the existing logic was causing all other transactions (payments, all processing transactions) to not be parsed and collected on our end
- fixed this issue by grabbing `transactionCode` in a non-conditional way to ensure we get all transactions
