The income account should be associated to transaction

[abouolia]

The income account should be associated to estimate, invoice, credit note transaction and takes the default income account from the selected item.

Even if the income account being changed from the item wouldn't affect the old transactions to update the new transactions should be update income account on all old invoices in bulk.

Adding bulk endpoint to update invoices (for instance) would help a lot to complement this feature.
