Title: Fix image sub query

As I said in #5.

`Arizona Diamondbacks` doesn't have `/common/topic/image` value, so it was filtered out. We should set an `optional` flag on that sub-query to make sure it doesn't filter out results.

And cached `teams.json` was generated with the rake task, no modifications.
