Both the parameters 'www_admin.api_embedded_forcearray' and
'www_admin.api_links_forcearray' were created long time ago
to have API backward compatible.
But the consistency of the returned values is a priority,
so we have to get rid of this option and keep the behavior
of the current default:
* always return an array
* always return lisk as an array
