Fix restoring network mode preference on reboot

When a user sets the option to use only 2G networks (for GSM networks) or its
equivalent for CDMA networks, each reboot erases that setting. That forces
the user to re-select the same option after each boot.
This (very simple) patch fixes it.

SMSDispatcher: Fix determining the defaultSmsApp for proxied messages

We can't rely on the calling UID, since for re-broadcasted texts that'll
always be the telephony itself; so if called by the framework, use
the sentIntent creator to determine which app originated the message

telephony: do only run setCellInfoListRate for RIL version >= 8
old libraries like those from MR0 don't support this and sending this command causes endless wakelocks
