Tax validation causes unwanted change in Purchase Invoice Item Tax Template

[konradbr]

Information about bug

The following alert is displayed when a tax template is chosen which has a validity start date later than the invoice date:

Item Tax template updated as per validity and rate applied.

This is unwanted behaviour, as e.g. some invoices will span two tax rate validity periods and the tax on one item will still be calculated according to the old tax rate, while the tax on another item on the same invoice will be calculated according to the new tax rate. This is especially important on invoices for subscription services (such as domain names, for example).

While such an alert is acceptable, it should not modify the user's selection in the invoice items, causing the calculated total to become wrong.
