tax identifier not picked up in generated invoice from purchase
as indicated https://discuss.tryton.org/t/party-identifiers-as-references/1210
We have invoices created that misses [at times] the tax identifiers.
The easiest way to reproduce this to add, on the demo database
the following identifiers on Saber:
"" "08044100"
"VAT" "FR12345174403"
then create a purchase, then confirm it.
The tax identifier in the generated invoice is blank
where it should be set to "FR12345174403"
