Bug 1051715 - [Telephony] Show correct phone number in temporary mode clir

When making a call with temporary mode clir, reference-ril adds 'i' or 'I' after the number. We should get rid of that in emulator modem. Otherwise, the number will not be a valid string because it contains the illegal character.
