Don't run onboarding if LND is already running locally
Don't run onboarding if LND is already running locally

The onboarding settings are only relevant if the user wants to connect to a
remote LND or have Zap run LND. If the LND is already running locally, the user
is capable of separately configuring it.

This does not support the case of connecting to a remote LND while running LND
locally, but I can't think of a reason why someone would do such a thing. In
such a case, they could quit LND, start Zap, then re-start LND.
