[IMP] test45 should not depend on previous tests

./odoo-bin -d db --stop-after-init --test-enable --test-tags=.test_45_xml_import_no_duplicate_partner
falliva perché non trovava il partner, visto che gli altri test non
erano stati eseguiti. Se manca il partner, viene importato l'XML due
volte.

Incluso fix odoo/odoo#71920, altrimenti il test
non passa.
