OCPP: if setting WebSocketPingInterval is NotSupported in nightly, ocpp setup will fail

[jeffborg]

Describe the bug

run nightly and evse rejects this line

evcc/charger/ocpp/cp_setup.go

Line 155 in 095fa42

return cp.configure(KeyWebSocketPingInterval, "30", timeout)

before this was not an issue it now is due to being in return position

Steps to reproduce

1. run nightly
2. if setting WebSocketPingInterval is not supported by your ocpp evse
3. then evcc will fail setup here because this command on this line is rejected

   evcc/charger/ocpp/cp_setup.go

   Line 155 in 095fa42

   return cp.configure(KeyWebSocketPingInterval, "30", timeout)

Configuration details

Any occp charger which rejects the WebSocketPingInterval configuration
