[IMP] account: mark invoice as sent once pdf generated

Before this commit, the invoices were marked as sent only when
sending them via email or post.

After, it is mark as sent once the PDF is being generated via the
send&print wizard, as it becomes computed based on the presence of
the PDF.

Rational, we want to consider a generated invoice via the
send&print wizard as being sent as it can be printed/downloaded.

This also makes the invoice available in the portal.
