henrika a125d7d7ad Changes default audio mode in AppRTCDemo to MODE_RINGTONE.
Also prevents that we try to restore audio mode when it has not been changed.

TBR=glaznev
BUG=NONE
TEST=AppRTCDemo and verify that volume control switches from "Ringtone to Phone" mode when call starts and switches back to Ringtone mode when call ends.
