Bug 1010104 - [Dialer][Call Screen] Baseline of the contact name when applying the fluid font size

```js
switch (scenario) {
case SINGLE_CALL:
  initialLineHeight = _SINGLE_CALL_LINE_HEIGHT;
// ...
default:
  return;
}
view.style.lineHeight = initialLineHeight * _getDefaultFontSize() +
  (maxFontSize - newFontSize) / 2 + 'px';
```
