It seems like we should be able to guard against pretty much any issues without resorting to try/catch here. I think we should add a componentDidCatch to the parent component, though.

I think we are safe as well, but I through it in for good measure to ensure we always get an itemList returned.

Ideally, try/catch should be reserved for exception handling rather than for flow control. I don't think it hurts in this case, but it can get overused.

We should probably add a test case with some bad data to validate these new code branches.

* Remove try/catch
* Add test for comparing to null values in the sort

I will follow this up with a componentDidCatch in the React tree to catch exceptions in the future.
