Opening a Pull Request Fails on First Attempt

[jannesblobel]

Description

When opening a Pull Request from Colibri for the first time in a newly loaded repository, the PR is not created on GitHub.

The UI switches from Open PR to Show PR, but:

• No toast notification appears
• No Pull Request is actually created

After reloading Colibri and trying again, the PR creation works correctly.

Steps to Reproduce

1. Load a new repository into Colibri. use this one https://github.com/jannesblobel/issueNo69
2. Make a change in the README.
3. Create an annotation.
4. Click Open Pull Request.
5. Wait until the button changes from Open PR to Show PR.
   • A toast notification is expected here but does not appear.
6. Check GitHub → No PR has been created.
7. Copy the Colibri room URL.
8. Reload Colibri using the same URL.
9. The button now shows Open PR again.
10. Click Open PR.
11. Colibri switches to Show PR and a toast notification appears.
12. Check GitHub → The PR is now created.

Expected Behavior

• The Pull Request should be created on the first attempt.
• A toast notification should appear confirming the PR creation.
• The UI state should match the actual PR status on GitHub.

Actual Behavior

• The first attempt fails silently.
• No PR is created.
• The toast notification is missing.
• The UI switches to Show PR even though no PR exists.
• After a reload, the process works as expected.
