SessionStore: Propagate database errors to express-session

Browse source 
Send a 500 HTTP status code to the client if the session entry could
not be fetched from the database. This is useful in case the database
is busy and can't respond to the query in time. In this case we want
to abort the client connection as soon as possible.
