[15/21] branch: stop modifying `log_all_ref_updates` variable

Commit Message

In "branch.c" we modify the global `log_all_ref_updates` variable to
force creation of a reflog entry. Modifying global state like this is
discouraged, as it may have all kinds of consequences in other places of
our codebase.

Stop modifying the variable and pass the `REF_FORCE_CREATE_REFLOG` flag,
which has the same effect.
