Prior to this change, if the user use a full refund option and choose a document type different than default one, the default document type was use regardless of the choosen one. This was broken on this commit https://github.com/odoo/odoo/commit/dfd01b8c5c7e1177f37bf199790a0732a61eed78#diff-1369ca152be95632086495cfcfbd54a0d18d893c2389670ff1d516f1596f3e0d We also fix the journal that is being used to get the available document types, it's not common to change the journal but it could be changed. closes odoo/odoo#82670 Signed-off-by: Josse Colpaert <jco@odoo.com>
