Bug 925404 - [B2G] [SMS] Always include the phone number in the SMS Thread UI, even if the carrier is known. r=schung

* Using new phone format everywhere;
* Using different color for carrier name in the thread view header;
* Removed a bunch of unsed code.
-> Maybe you should just use data.number here?
But we need to render highlighted number not just number (```data[key + 'HTML']->numberHTML```) that was created line above.
