[IMP] sale: change default invoicing policy to 'ordered'

Currently, the default invoicing policy is based in `delivered`
quantity since commit: https://github.com/odoo/odoo/commit/3ad4abe171e8e7e86ed0e7b7f000e734d8a2ad92
but due to that onboarding flow is often broken/very complex.
hopefully the statement 'in countries with anglosaxon accounting, that's mandatory' is exagerated.

So in this commit, Default invoice policy is set (back) to
'Ordered quantity'
