The recent --negotiate-only option would segfault in the call to oid_array_for_each() in negotiate_using_fetch() unless one or more --negotiation-tip=* options were provided. All of the other tests for the feature combine both, but nothing was checking this assumption, let's do that and add a test for it. Fixes a bug in 9c1e657a8fd (fetch: teach independent negotiation (no packfile), 2021-05-04).
