notification: properly handle cnx and lifetime of the hijacked session When we create a session for the notification rendering, we need to 1) give it a cnxset 2) commit and close it after we're done 3) restore the original session for subsequent notifications This changes the ordering of actual mail sending, since there are several different commits involved, but I don't see a way to fix that short of restoring hijack_user. Related to #2934523

notification: fix session creation (closes #2934523) Session() takes a user and repo, not repo and user.
