Queue invoices for Xero sync when changes are made to authorised document
The fairly recent option allowing users to make changes to authorised documents is handly, changing invoice date without undoing for instance.
But in reality, we want most of these changes to propagate to Xero. However, changing the invoice date does not trigger a sync. And in fact, it is not possible to manually request a resync. This doesn't make sense: if we are allowed to change an authorised document, it should trigger an update to Xero, otherwise, what's the point? Currently, it does not actually avoid having to undo the order and reinvoice it.
