Ensures ProfileTrustAgent properly grants/revokes trust [2/2]

Notifies the ProfileTrustAgent when a WiFi/BT event was triggered even
if no new profile was selected so the trust agent can grant/revoke trust

Filters out the multiple network state change notifications to make sure
we notify the trust agent only when the event that the profile
is tracking actually happened
