Update unsafe React lifecycle methods

[Jason Kleinert]

React is deprecating 3 of their lifecycle methods in the upcoming version 17 release. These are:

• componentWillMount
• componentWillreceiveProps
• componentWillUpdate

We should determine if it's worth updating this app or not. I know we hadn't really planned on updating the React version, but may have to eventually.

For now the code will continue to work with deprecation warnings and possible bugs. We need to identify where these are used and update our code with the recommended alternatives. Guidance found here: https://reactjs.org/blog/2018/03/27/update-on-async-rendering.html
