[gnome-contacts] Fix check is_callable to check for CALL not STREAMED type.

[Alexander Larsson <alexl src gnome org>]

    Fix check is_callable to check for CALL not STREAMED type.
    
    Replace custom code with "caps.supports_audio_call
    (TelepathyGLib.HandleType.CONTACT)":
    - fixes the non introspectable call
    - removes the check on obsolete STREAMED type (all the other sources in
    gnome-contacts now switched to CALL type already, expect this leftover).
