[webrequest] set DBAPISession without cnx at initialisation time


Such session are necessary for minimal use of a Request. Setting on by default
allow simplification later linking with a full featured DBAPISession or
equivalent. This was not possible before as all session was tracked by session
manager. They are not tracked anymore since aa709bc6b6c1 and we can safely
create them by default.
