InCallUI: Use NoActionBar theme for InCallActivity

InCallActivity and MsimInCallActivity has actionBar, however the actionBar
shows faster than the activity, so even though activity hide the actionBar,
it still display for a moment.

Use NoActionBar theme as the parent theme for InCallActivity in stead of
Theme.Holo, and set the theme with actionBar for MsimInCallActivity.
