Merge #13522: [tests] Fix p2p_sendheaders race

75848bcf40 [tests] Fix p2p_sendheaders race (John Newbery)

Pull request description:

  p2p_sendheaders has a race in part 1.3.

  part 1.2 sends a block to the node over the 'test_node' connection, but
  doesn't wait for an inv to be received on the 'inv_node' connection. If
  we get to part 1.3 before that inv has been received, then the
  subsequent call to check_last_inv_announcement could fail.
