Reporting: Save test results after a test execution

[dmarvp]

Summary

After the work done on @source-api:, skill-testing should take the Jest result object and send it to the new endpoint (along with other needed parameters) to save the test execution results.

After doing the update, we should update the skill-testing version in bst and release a new beta to test it. Ask @ecruzado about the usual procedure for this.
