`simpleSort` with `useJavascriptSorting` don't support `dotNotation`

[Losses]

Here's the implementation:

LokiJS/src/lokijs.js

Lines 3295 to 3301 in 25b9a33

	if (options.useJavascriptSorting) {
	return this.sort(function (obj1, obj2) {
	if (obj1[propname] === obj2[propname]) return 0;
	if (obj1[propname] > obj2[propname]) return 1;
	if (obj1[propname] < obj2[propname]) return -1;
	});
	}

But the unit test is trying to use this feature here:

LokiJS/spec/generic/ops.spec.js

Lines 251 to 253 in 25b9a33

	var results = coll.chain().find(
	{ 'nested.count': { $in: [15, 73] } }
	).simplesort('nested.count').data();
