Fix ViewPropTypes error

[MGYaroslav]

After updating my project to expo ~41.0.0, react-native-web was also updated and in it ViewPropTypes was deprecated.
So I have an error - " Module not found: Can't resolve 'react-native-web/dist/exports/ViewPropTypes' in 'MY_PATH/node_modules/react-native-hsv-color-picker/src' "

Here is an issue from react-native-web:
necolas/react-native-web#1537

P.S. I've tried workaround from that article, but it breaks this picker, I can only move picker dot, but after click I've got saturation/hue/value = NaN
