Lnd invoked `onError` even though `onResponse` has already been called for startLnd

[hsjoberg]

This causes the follow error on iOS:

Invariant Violation: No callback found with cbID 1617 and callID 808 for LndMobile.startLnd - most likely the callback was already invoked.

I think the issue is related to this and this,
