refs: drop git_default_branch_name()

Browse Source 
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`.
