Change tints, backgrounds on incoming call icons.

- Also tweaked icon tints for the InCall buttons, to make them less
prominent in the disabled state.
- Strengthened the logic around setting the audio button's enabled
state in the call button fragment. Before, updateAudioButtons() was
setting the audio button to be enabled after setEnabled(false) was
called on the fragment, causing it to be set to disabled notably
later than the other buttons.
