Merge bitcoin#29688: test: remove duplicated ban test

e30e862 test: remove duplicated ban test (brunoerg)

Pull request description:

  Test the ban list is preserved through restart has been done by both `rpc_setban` and `p2p_disconnect_ban`. Since `p2p_disconnect_ban` does it in a more elegant way, we can keep only it and remove the other one.
