[FIX] partner_autocomplete: fix Partner Autocomplete not working on VAT

Since b1f1f21, Partner Autocomplete wouldn't work anymore on VAT numbers
as the field on which the widget was added was replaced by another one,
without the widget.

To fix this, the widget will now be added dynamically in `_get_view` so
that it happens after modifications made through view inheritance.

Another way of fixing this was proposed in b14a3af, but required an
upgrade of the `base_vat` module.
