Create a new internal campaing for members and their fees. (#527)

* Create a new internal campaing for members only.
This way we can pay the annual fees using stripe and the subscriptions we support.

* Do not insert the campaign if there is no beneficiary.
We cannot execute this on an empty db. There are simply too many records to provide if the db is empty (person, city, country...)
