fix: wait for GitHub import re-translate after body edit (#2294)

## Summary
Full Suite shard 3 failed `GitHubImportAutoTranslate` re-request after
body edit: mock call count hit 2 before `translations.get(1).title`
committed. Wait for the map entry.

## Test plan
- [x] Local re-request test green
- [ ] PR gate + Full Suite
