TextFields lose MDC controlled classNames when className prop is passed

[jamesmfriedman]

<TextField className="foo"/>

When this field is typed in, it will appear focused until it re-renders on value change. The TextField will then lose its focused class.

One potential fix is to manually assign the classes. Another one is to mimic the Ripple component and collect all MDC classes to pass along.

In 1.8.3 TextField always loses class name.

@NSWIDER do you have a repro of your issue? The className on TextField gets added to the TextField container, not the input itself.
