There is no point in creating a new invoice without products, thus we
were forcing users to always use the “Add product” button for no reason
other than it was easier for me….
I wanted to add the product inside ServeInvoice, when the slug is “new”,
but then it tried to compute the invoice total without price or quantity
and it failed. Thus, i add that product after it has done the
computation query.
