crospts: Fix the error when no data in results-chart.json

If the CrosPTS failed to run the tast test, there is no data in
results-chart.json. This causes the generating CSV failure.
Fix this error by skipping the no keys in JSON object.
Skip the data uploading, if there is no any results chart data produced.

BUG=b:323753496
TEST=./run_crospts.py -p all -u cns <DUT> with an error empty
results-chart.json
