[FIX] purchase: ensure all vendor bills are gathered from purchase order

The 'vendor bills' stat button on purchase order, once clicked, will
have a specific behavior depending on the invoice count :
    0 : open a new invoice with pre filled fields (not saved yet)
    1 : open the form view of the invoice
    2+: open the list view of the invoices.

Before this commit, the invoice count was computed with an environment on
the current user. That means a record rule could make the invoice count
lower than the real count and so give an unwanted behavior. Ex: create a
new invoice even if there is already one created because the user cannot
see the other people's invoices.

After this commit, the action_view_invoice with make an explicit read()
in database to fill the cache with all the purchase order's invoices and
make sure the count is the real one.
