Inspection required before delivery isn't working for item variants (#9362)

* makes `copy_attributes_to_variant` to not ignore "Table"

* fixes test cases - `test_auto_material_request` and `test_auto_material_request_for_variant`

* adds test case - tables in templates should be copied to variants

* [ci] use deprecated trusty build for now
