Bugfix: arrays returned as objects like {"0":... }

[Nadrieril]

Sometimes an array gets returned as {"0":..., "1":...} instead of [..., ...]. Furthermore, this behaviour only appears at the root; when nesting arrays only the root is affected. I have seen multiple users being confronted to this bug. It is pretty annoying.
This is how I understand the code: In this part of the code, you assume that empty($rs) && array() === $this->getRoot() imply that the root is an empty array, that should then be returned as {} instead of []. But you don't actually check that you are at the root. That is the check I add.

You should start by adding a failing test

I can add a failing test, but tests fails anyway with the actual codebase.
