Fixes #3714: Update react-collapse and react-motion for React 16 support

[legrego]

Description

Updated versions of react-motion and react-collapse to be compatible with both React 15 & React 16

Motivation and Context

Fixes #3714

How Has This Been Tested?

After updating these versions, I tested using the petstore sample as-is, to confirm that it still worked with React 15.

I then tested this in a React 16 based project, and verified that I could use swagger-ui in this context, without receiving the proptype errors described in #3714

Screenshots (if appropriate):
