Created by: terinjokes

• Sourcegraph version: 2.8.9 (server)
• Platform:
  • Code Host: Bitbucket Server

Steps to reproduce:

1. Setup a Sourcegraph Server instance
2. Configure Bitbucket Server code host
3. Repos clone 🎉
4. Administrators still see the "Configure repositories and code hosts to add to Sourcegraph Server." toast.

Expected:

Toast goes away. Sort-of like ihob.

Actual:

You keep getting toast, even when you want burgers.
