Use latest matching deployment

[byronigoe]

Download the most recently uploaded package that matches the version instead of always choosing the most specific deployment

Thanks for the PR!
it seems reasonable to choose the latest but not more specific version. We have not used the MS official service before so I am not sure about the behavior of official service, but I checked the code-push-cli doc and didn't find any information about more specific target version should be prefered to version range.
As regards the changes here, I'll need to double check the rollback & prompt cases, not sure about whether sorting by created_at works for them.

It looks like it always create new packages for rollback & prompt cases, I guess use created_at is fine.
Would you mind helping with the lint issue? I'll merge this PR once it passes CI.

btw: since we only need the last array item, maybe _.last(_.sort(...)) can be faster that .reverse()[0]. It might be even better to sort and findOne with sql query, but I suppose current solution is good enough for addressing the issue itself.
