The `git_default_branch_name()` function is a thin wrapper around `repo_default_branch_name()` with two differences: - We implicitly rely on `the_repository`. - We cache the default branch name. None of the callsites of `git_default_branch_name()` are hot code paths though, so the caching of the branch name is not really required. Refactor the callsites to use `repo_default_branch_name()` instead and drop `git_default_branch_name()`, thus getting rid of one more case where we rely on `the_repository`.
