Set upper interval as included in product count.

This is a fix for #376

[romainruaud]

Seems that you were right.

Something is weird here :

Product A is 68$
Product B is 69$
Product C is 69$
Product D is 69,10$

When building the Slider, the intervals values are given as this :

{"value":68,"count":1}
{"value":69,"count":3}

On the slider if I choose "67-69" : it show 4 products, meaning that the product D is included. So my PR is OK here. Without this PR the slider shows 1 product only.

BUT, if I submit the page, I only see products A B and C. Because the query sent to ES is :

"query":{"range":{"price.price":{"gte":"67","lte":"69"}}}

Which cannot match a product having a price of 69.10$

So I think this PR should not be merged as is, but rather be reworked a little to cover all cases.

If I set a product to 69.10$ and select eg 67$-69$

As you have said this PR need to be reworked.
I close for being inactive since a while.
