Fix an edge case in Sabre's release valve (#13114)

* Fix edge case in Sabre release valve

If a Sabre trial does not find a set of Swaps to route nodes, the "release valve" adds Swaps to route the two-qubit gate in between the the closest two qubits. In rare cases, this leads to _more_ than one gate being routable, which was not handled correctly previously.
