Stars change even if onChange fails and the value does not change

[s7dhansh]

If the star value remains unchanged even after clicking the stars (due to a failure in the onChange method or otherwise), the stars retain their changed state, instead of reverting to the original.

I think

react-stars/src/react-stars.js

Line 91 in b3455bd

stars = Math.round(this.state.value)

must have this.props.value and not this.state.value. Let me know and I can push a PR.
