Bug 

**What is the current behavior?**

React DOM crashes when `<option>` contains three interpolated value if one is a conditional. 

Reproduction: https://jsfiddle.net/0opjvycp/ 

1. Change the value of the `<select>`
2. React crashes with `NotFoundError: Node was not found` 

From what I can tell, the conditional value is necessary, and it must be three interpolated values. 

**What is the expected behavior?**

React should not crash. 

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

React DOM 16.2 and 16.0. I think this worked in 15.6 - https://jsfiddle.net/mrwkmuqc/ does not crash
