IMS-VT: Set audio route correctly for Video/voice call for outgoing calls

- Set speaker phone flag for outgoing calls when one of three conditions
  is met - speakerPhoneOn flag passed into the placeOutgoingCall is true
  or speaker is auto enabled for video calls or phone is docked.

- Route audio to earpiece in DIALING state if call is a Voice call and
  bluetooth or wired headset is not connected. This fixes an issue where
  if we make a first video call and second outgoing call is voice, audio
  is routed to speaker which is not expected.
