Merge #19649: Restore test case for p2p transaction blinding

Browse Source 
566aada386 Test that wtxid relay peers add wtxid to reject filter (Gregory Sanders)
0fea6ede1b Restore test case for p2p transaction blinding (Gregory Sanders)

Pull request description:

  Introduced in ca10a03add then erroneously removed in 8d8099e97a. The restored line is how we are
  checking that the node will still re-request a specific txid given a witness-related failure.
