fix: Move shards json to result directory

[adamfilipow92]

Fixes #1475

Test Plan

How do we know the code works?

1. Run flank with android or ios test
2. Wait until results-directory is created
3. Open the results directory and check *_shards.json exists
4. If disable-results-upload not set, check shards file exists in gcloud bucket
5. Flank shouldn't upload shards file to gcs if disable-results-upload set

if localResultsDir is different than default, we should not add file to resultsDir. We have similar logic in the whole app
