refs: make sha1 output parameter of refs_resolve_ref_unsafe() optional

Allow callers of refs_resolve_ref_unsafe() to pass NULL if they don't
need the resolved hash value.  We already allow the same for the flags
parameter.  This new leniency is inherited by the various wrappers like
resolve_ref_unsafe().
