[FIX] account.invoice report: show customer description of payment term

The payment term description (note) is meant
to be shown to customers. Restore it in the
default invoice report, as it was in 7.0.
If empty, assume the payment term is meant
to be hidden from customer, and do not show
anything.
By default the description includes the name
of the payment term, so no need to keep both.
[FIX] account: give "Invoice" users access to "Invoice Analysis" Report.

This access is required in order to display the amount invoiced on partner form
