- This will only allow `GetDeletedBranchByID` to return deletedBranch
which are on the repo, and thus don't return a deletedBranch from
another repo.
- This just should prevent possible bugs in the futher when a code is
passing the wrong ID into this function.
- Update default branch if needed
- Update protected branch if needed
- Update all not merged pull request base branch name
- Rename git branch
- Record this rename work and auto redirect for old branch on ui
