Fixed kanban filter on kanban field metadata item (#12367)

This PR fixes an edge case where we couldn't apply a filter on the field
metadata item that is used by a kanban.

As this has already been fixed for tables with groups, this PR just uses
the same technique.

Fixes https://github.com/twentyhq/twenty/issues/12311
