resolve_ref_unsafe(): handle the case of an SHA-1 within loop

There is only one "break" statement within the loop, which jumps to
the code after the loop that handles the case of a file that holds a
SHA-1.  So move that code from below the loop into the if statement
where the break was previously located.  This makes the logic flow
more local.
