Android Crashes with stepCount={1} #88

Also encountering this on both iOS and Android. I have pages of varying lengths, and want to keep a visual consistency by always having the page count, even if there is only one page.

I believe this error is caused by

const animateToPosition = (this.state.progressBarSize/ (stepCount - 1)) * position;

in onCurrentPositionChanged

When stepCount is 1, then it is dividing by zero, which results in an invalid value for the progressBar width.

No progress bar should be needed if there is only 1 step.
