fix rare panic when local index collision happens (#1191)

Browse Source 
A local index collision happens when two tunnels attempt to use the same
random int32 index ID. This is a rare chance, and we have code to deal
with it, but we have a panic because we return the wrong thing in this
case. This change should fix the panic.
