Downshift: getButtonProps is not a function

[gsimone]

As of version v1.31.1 we get getButtonProps is not a function.
There supposedly is an alias since the change tonight to getToggleButtonProps, but something is not working as expected, looking through the code right now, will update if I find the problem.

The aliasing wasn’t not done properly (ref to Line 552) as the getButtonProps don’t get passed down along with getToggleButtonProps to the render function.

This change was introduced as a patch and need to be rectified as soon as possible.

Would you like to make a pull request @gsimone?
