[souredoutlook]

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

1. Create a configuration for GitHub Org A and GitHub Org B
2. Add repository to configuration for GitHub Org A
3. Transfer repository to GitHub Org B
4. Observe that the repo is listed in configuration for GitHub Org A with URL for GitHub org B
5. See that repo is available to be added to configuration for GitHub Org B

Expected Result

When a repo is transferred to GitHub organization B I would expect the repo to be removed from Integration configuration for GitHub org A

Actual Result

The repo remains in configuration for GitHub org A but in a broken state (can't import codeowners for example).
