Comparator test fails if args are switched

[STRML]

In work I am doing to solve #33, I noticed that this test will fail:

  it('returns true if Comparator says so even on primitives (switch arg order)', function () {
    var valueA = { a: 1 };
    var valueB = {
      a: new Matcher(function (value) {
        return typeof value === 'number';
      }),
    };
    assert(eql(valueA, valueB, { comparator: matcherComparator }) === true,
      'eql({a:1}, {a:value => typeof value === "number"}, <comparator>) === true');
  });

This only changes the argument order from the existing test. This is because only the left-hand side is checked as a primitive, when really both sides should be to ensure identical behavior.

I will fix this as part of a PR, but I believe we'll end up breaking null comparator behavior.
