Did #2 fix this? Should results_presentation now work with multiple shards?

Is merging the json files of multiple shards the only thing we need to do to make results_presentation work? If so, then it should be working. Is it easy to test and see?

I think this is working now, e.g. chrome_public_test_apk here: https://build.chromium.org/p/chromium.linux/builders/Android%20Tests/builds/44045
