Logan Daniels 3559e42c55 Make sure VirtualizedList's windowSize is greater than 0
Summary:
Setting `windowSize = 0` doesn't make sense. Let's make sure we catch this problem in the constructor so that it doesn't cause inexplicable list behavior.

Also fixed an invariant in `VirtualizeUtils` that is meant to prohibit non-monotonically-increasing offset arrays. As written, the invariant condition can never actually be violated.
