trampoline: prevent adding ourself on the route

Browse Source 
Followup #10541.
Fixes tests.regtest.TestLightningSwapserver.test_swapserver_forceclose.

In the regtest bob would now signal trampoline support due to #10541 and
include Alice into the invoice trampoline as he is connected to Alice.
Alice would then try to add herself onto the trampoline route, causing
the payment to fail.
