Elastica\Filter\Bool does not work with other Bool filters as children

[sten]

Given a Elastica\Filter\Bool object, if you add other \Elastica\Filter\Bool objects as should or must children, the query is not correctly generated. The toArray method is not called on these Filter\Bool children.

@ruflin I fixed the bug and I tried to push my local branch to create a pull request, but I get the following error:

remote: Permission to ruflin/Elastica.git denied to sten. 

How can I resolve this? Thanks!

[ruflin]

The problem is that you push to the ruflin/Elastica instead of your own fork. You must push to your own fork and open an pull request from there.

I am sorry for the trouble! I forked it and made a pull request in my fork. Thanks for the help!
