This PR refactors the non-generic part around ObjectFilterDropdown which
has been left in statu quo for months.
It also removes unused components.
Overall this PR is doing renaming and it re-organizes files into their
relevant modules.
This clarifies a lot what's at the intersection between
object-filter-dropdown and views modules.
This PR was originally about removing any remaining useEffect around
ObjectFilterDropdown but there wasn't any.
