[fix] ScrollView passive event listener warning
[fix] ScrollView passive event listener warning

'touchstart' and 'touchmove' listeners added to the document will
default to 'passive:true' (so that calls to 'preventDefault' will be
ignored). Source https://www.chromestatus.com/features/5093566007214080

To support 'scrollEnabled', listeners are bound to the underlying
ScrollView DOM node to avoid being passive.

Fix #477
