Telephony: Guess radio tech

If RIL returns radio_tech_unknown IccCardProxy
needs to guess radio tech family.
It will do so based on present uicc applications.

Make sure that all pathes update IccCardProxy
radio tech, since it has its own logic for determining
app type, which might change even when PhoneProxy
ignores the change
(An example of this would be umts->unknown->umts change)
