Transifex-integration bot is immediately closing its unmerged pull requests

Update:
The bot is closing the pull requests when another resource has been fully reviewed, creating a new pull request instead of updating the existing one.

  1. Resource A fully reviewed
  2. Bot opens pull request A with resource A
  3. Github action changes merge target
  4. Resource B fully reviewed
  5. Bot closes pull request A
  6. Bot deletes branch from pull request A
  7. Bot creates pull request B with resource B

Example:
PR #3356: Pull request for Russian resource units.json
PR #3357: Pull request for Russian resource interface.json

Instead of appending interface.json to #3356, it creates #3357 as a separate PR, and for some reason closes #3356.
