When creating new contact coming from a mailing list a default_list_ids
context key is set. It is used to give a default value to list belonging
and also to compute opt_out.
However subscription_ids field is displayed on contact form view, allowing
to add the contact to mailing lists. We may end up in situation where a list
is given twice to a contact: once through default_list_ids and once through
subscription_ids field manually completed by users.
In this commit we therefore merge those two values when creating contacts.
Also improve some wording while we are at it.
