bug: reverse translation outputs in report.jsonl when no translation used

[leondz]

steps

1. do a run (e.g. garak -m test -p test.Test -g 1) with no translation enabled
2. look in the output report.jsonl

expected behavior

report.jsonl doesn't mention translation

actual behavior

report.jsonl does mention translation
