------------------
- Fixed `MCMeetingDocumentGenerationHelperView.get_grouped_items` when using
`excluded_values/included_values` parameters together with `unrestricted=True`,
unrestricted was not propagated to sub methods giving nonsense results.

- Added parameter `additional_catalog_query={}` to
`MCMeetingDocumentGenerationHelperView.get_grouped_items` making it possible
to pass additional traditional portal_catalog query to filter items.
