- Only send a review request based on the code owner file if the code
owner user has read permissions to the pull requests of that repository.
- This avoids leaking title of PRs from private repository when a
CODEOWNER file is present which contains users that do not have access
to the private repository.
- Found by @oliverpool.
- Integration test added.
