annotate sat_pubsub/error.py @ 417:412d26a9b2c2

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.
