Cannot select menu items on mobile

[kelvin-tran]

There seems to be a bug preventing menu items from being selected on mobile only. Selecting (ie, clicking) the menu item does not result in the onChange method being called.

Seems to be a duplicate of this react-select issue: JedWatson/react-select#1036 (importing components from react-select and not react-select-plus seems to fix it, but then we lose support for option groups).
