Currently we report pass on request submit job, but in the report results we fail, because there is no results.xml to parse.

As this problem could happen due to some infra issue on testing-farm side I think we could just retry the submit job if it errors due to result.summary: `Failed to discover tests, TMT metadata are absent or corrupted`
