Initate spark payments from background

Previously payments could block and we would end up waiting for the
payment to complete before ever returning. This could cause our payment
metadata to get screwed up as we weren't able to mark it as a
trusted/rebalance payment immedaitely. Now we generate the id ourselves
and init the payment in the background so we do not block on this and an
safely set our payment metadata.
