Describe the bug
In the date range component, the isEqual function is passed an object with an object as the value in the key value pair
const d1 = new Date("1-15-2020);
const d2 = newDate("2-15-2020);
const d3 = new Date("3-15-2020);
isEqual({start: d1, end: d2}, {start:d1, end:d3} === true

To Reproduce
Steps to reproduce the behavior:
https://codesandbox.io/s/stoic-bush-jsrrt?file=/src/App.js:164-184
Use a date range as a controlled component; the on change methods will not fire because it is detecting the values are equal.

Expected behavior
Clicking the button in the sandbox above should set the date properly; this can be fixed by adding a JSON.stringify check to the isEqual function
