Associated Savings Account With Not Displaying For Goals

When a goal is associated with a saving account, it is not displayed when loaded from a file.

In BudgetedGoalEntryWidget::populateWith:

const auto ba{lookUpBankAccount(goal.source(), this->accounts_)}; // TODO: this should probably be the parent account and not the budget item's ledger account

Reproduce: Create a goal associated with being stored in a savings account, save it to a file, load it, and the association is not displayed, though it's stored in the file.

Seems that when re-coding the goal account parent information, it does not work in this one case.
