[DataQuery] Less than with nullable date/int

[cheng93]

Description

Given the following data

[{age: 1}, {age: 2}, {age: null}]

when the oData query filter, $filter=age lt 2, is applied, you would not expect the last value to show up

Steps To Reproduce

https://stackblitz.com/edit/angular-rsabply1?file=src%2Fapp%2Fproducts.ts,src%2Fapp%2Fapp.component.ts

Set the filter to be less than today. You can see that undefined is filtered, but not null

I think it's because underneath, it's using JS default filter, i.e

[null, undefined, 1, 0].filter(x => x < 2) // [null, 1, 0]
