import_data() does not work for many2many multiple values on object xml_id

according to the technical memento, you should be able to reference multiple xml_id in the same field for many2many fields but it does not work.

this works fine with the database_id

see attached example modules

to recreate the problem:
1) create a BASE system with no demo data
2) install 'import_mod_problem' module first
3) install 'import_mod_problem_data' second to see error
