[DatePicker] Triggering react warning in console when setting date

[nathanmarks]

TextField is changing a uncontrolled input of type text to be controlled. Input elements should not switch from uncontrolled to controlled (or vice versa).

Pops up in console when you use datepicker, investigating now. It is due to

value={this.state.date ? formatDate(this.state.date) : undefined}

When the date property on state is set, it switches the component from uncontrolled to controlled 👎 🎱
