NetworkNotificationManager: correctly handle existing notifications

Browse Source 
This patch corrects a regression added by commit fd35080555 that did
not take into account the case of multiple notifications shown for a
single network id. Given how network notifications are triggered, it can
happen that NO_INTERNET and SIGN_IN notifications are both triggered for
the same network when captive portal detection is slow.

Contrary to the situation before commit fd35080555, a notification
priority order is introduced so that SIGN_IN always overrides
NO_INTERNET, and NO_INTERNET is ignored if SIGN_IN is already present.
