Parallelize queries for distance and calories in query() in Android

[dariosalvi78]

remove Tasks.wait() and run queries in parallel instead. This can likely speed up the multiple queries done when getting activities with distance and calories in Android. Unfortunately there is no trivial way to do it.

@dariosalvi78 I think that would be helpful to be able to just get calories and not distance. So that way we can request calories without request 'location' permissions to the user.

I agree, but it requires some changes, happy to receive a pull request if anybody wants to fix it
