celery: celery-run should only initialize app and sqlalchemy after workers have been forked

If app and SqlAlchemy were initialized before launching celery, the forked
workers would inherit the database connection ... and that doesn't work.

This could be handled by disposing the engine after forking the worker or
before each task ... but it remains unnecessary and wrong to initialize the
engine early when it isn't used, and then fork it.
