The unit test of sotringIndexing is not correctly implemented

[Losses]

The variable len is defined here:

LokiJS/spec/generic/sortingIndexing.spec.js

Line 307 in 25b9a33

var len = results.length;

But the value is not replaced here:

LokiJS/spec/generic/sortingIndexing.spec.js

Lines 316 to 320 in 25b9a33

	results = rss.chain().find({b:1}).simplesort('a', { disableIndexIntercept: true }).data();
	expect(len).toBe(6);
	for (idx=0; idx<len-1; idx++) {
	expect(loki.LokiOps.$lte(results[idx]["a"], results[idx+1]["a"]));
	}

Here:

LokiJS/spec/generic/sortingIndexing.spec.js

Lines 323 to 327 in 25b9a33

	results = rss.chain().find({b:1}).simplesort('a').data();
	expect(len).toBe(6);
	for (idx=0; idx<len-1; idx++) {
	expect(loki.LokiOps.$lte(results[idx]["a"], results[idx+1]["a"]));
	}

The code is testing the same result for three times, which is incorrect.
