[PATCH 2/2] remote.c: remove BUG in show_push_unqualified_ref_name_error()

In the case where a non-existent oid is given as the <src> for a refspec and the destination is unqualified, we end up hitting the BUG in show_push_unqualified_ref_name_error().

This is because before hitting this advise message, the <src> is passed through repo_get_oid() which, upon receiving a fully qualified oid, doesn't actually check the existence of the object and just returns found. This means that it's actually possible for the odb_read_object_info() call to return not found under normal usage and thus, it's not actually a bug.

Replace the BUG() with an advise() displaying a helpful message about the oid possibly not existing.
