import sat/wokkel modules only when making service:
when importing some sat/wokkel module, a reactor is installed. This can cause trouble when
using sat_pubsub along with other twisted plugin installing a specific reactor (which is
the case for SàT backend and Libervia).
This patch works around it by importing those modules only when making the service.
