Charts crashes when changing from playback to live mode

[jgalazm]

It happens after a while. This is the traceback of the error, there is an issue with "timeLine.setExtent" calling "charts.setSelection" since timeLine performs setState and setExtent is called in componentDidUpdate, which generates an infiniteloop..
I'm rolling back to when it worked and starting a new branch from there: e0c3605 to charts-refactor2

The problem appears here: 793cae6

and this is the traceback:

For now I'm just commenting brush operations on updateSlider.
