Update ynab5 demo budget so that budget import tests pass

The data has changed so there is a split transaction which has a transfer of 50
from checking to savings.

This adds a matching transfer from savings to checking account.
It leaves the checking account with 600 dollars, and savings with 250 which the tests have been updated to reflect.
