Use FLAG_IMMUTABLE on NetworkStackNotifier intents
FLAG_UPDATE_CURRENT was not helpful because:
- For the venue info notification, the only extra is the Network, and
the intent uses the network handle as identifier; meaning that two
matching intents would already have the same extra.
- The ACTION_WIFI_SETTINGS intent does not have any extra, so there is
nothing to update.
