[primary] refactor primary view handling of relation's label
to properly handle label optionaly specified in dispctrl (no more default set)
and use contextual translation by default.
Also, consistent handling in attributes, relations and sideboxes section.
Introduce new support_args function to use when possible instead of
try/except TypeError.
