av sync tries to restack orphaned branch

[windybranch]

I had some merge conflicts with 2 branches that I had adopted using av adopt. Manually rebasing them didn't have any issues.

Original branch tree: main -> landing -> landing-build

✅ I orphaned the branches to remove them from aviator
✅ av tree no longer showed the branches
❌ running av sync still tries to restack the orphaned branches:

 ⣽ Restacking landing-build...                                                                                                     
  Rebase conflict while rebasing  landing-build                                                                                     
  Failed to rebase "refs/heads/landing-build" onto "refs/heads/landing"

✅ I deleted the branches locally using git branch -D (the branches are already deleted off remote after the PRs were merged)
❌ running av sync still tries to restack the orphaned branch:

⣽ Restacking landing-build...
                               
error: failed to get branch "refs/heads/landing": reference not found

❌ running av sync --current on the new branch I'm trying to update still has the same error. I would expect it to sync only that part of the tree
❌ av tidy shows nothing to do:

✓ No branch to tidy

For anyone else experiencing this, the way to hack out of this situation is to:

1. Go to main and re-create the branches that av is trying to restack. In my case: landing and landing-build
2. Run av sync and it will come up with the rebase conflicts again
3. Run av sync --skip repeatedly until it finishes the restack

 ✓ Restack is done
Caught panic:

invariant error: cannot read branch state for empty branch name

Restoring terminal...

error: program was killed: context canceled

4. Switch to main and run av sync (yes to this is truck)
