Telephony: Fix the failure of copying SMS to SIM card for sub2

While copying SMS of sub2 to its SIM memory, in process of getting
current Phonetype will return default sub's(i.e,sub1's)Phonetype. But
we want to get sub2's Phonetype here.

To fix this, get current Phonetype based on subscription id

Test: manual - Copy SMS to SIM card of sub2
