- Uses shared FontSizeUtils to compute the new sizes
- Splits the font size changes and baseline into two different functions
- Removes unneccessary fake nodes from previous algorithm
- call_screen.js use the single-line class rather than a test that could change
- calls_handler.js and handled_call.js calls ensureFixedBaseline when necessary
- calls_handler.js scenario is always a second incoming call, the first one is handled by handled_call.js
- utils_test.js cleanup and jshintification
