`componentWillReceiveProps` does not reflect `isOpen` prop properly.

Nobody has claimed this yet.

The current [componentWillReceiveProps](https://github.com/maxs15/react-native-modalbox/blob/9928297925750e004af77b8e9f1b2cce0d799646/index.js#L106) function does not reflect the new properties accordingly.

If the `isOpen` property is modified, the `handleOpenning` function ends up comparing `nextProps.isOpen` against `this.props.isDisabled` in the open/close functions which shouldn't be the case.

It'd make more sense to pass in the current props and replace stuff like:
```javascript
close: function() {
if (this.props.isDisabled) return;
if (!this.state.isAnimateClose && (this.state.isOpen || this.state.isAnimateOpen)) {
delete this.onViewLayoutCalculated;
this.animateClose();
}
}
```

with
```javascript
close: function(nextProps = null) {
let props = nextProps || this.props;
if (props.isDisabled) return;
if (!this.state.isAnimateClose && (this.state.isOpen || this.state.isAnimateOpen)) {
delete this.onViewLayoutCalculated;
this.animateClose();
}
}
```

Or better yet, just move the `handleOpenning` function into `componentDidUpdate` instead.

Start in index.js around componentWillReceiveProps and handleOpenning, then trace how isOpen and isDisabled are used by the open and close functions. Reproduce a change to isOpen and verify that opening or closing responds to the new props without comparing isOpen to isDisabled.
