Before this commit, if there was a kanban view with a field with
widget="many2one" explicitely set, the legacy KanbanMany2oneField
was used. That field simply displays the name of the related
record, with no link.
In the wowl kanban view, we only use a FieldComponent if the
field is explicitely set, and we use a formatter otherwise. For
that reason, this commit simply removes the kanban special case
instead of re-introducing it. So by default, a many2one will be
displayed in a span, and if someone wants the link in the kanban
card, he has to set widget="many2one" (this wasn't possible before).
Temporarily, until we remove the fallback on the legacy field
registry, we need to add a "fake" entry in the wowl registry, to
prevent from fallbacking on legacy.
