peer: within loadActiveChannels, skip channel if FundingLocked not processed

Browse Source 
This commit fixes a bug to wrap up the recently merged PR to properly
handle duplicate FundingLocked retransmissions and also ensure that we
reliably re-send the FundingLocked message if we’re unable to the first
time around.

In this commit, we skip processing a channel that does not yet have a
set remote revocation as otherwise, if we attempt to trigger a state
update, then we’ll be attempting to manipulate a nil commitment point.
Therefore, we’ll rely on the fundingManager to properly send the
channel all relevant subsystems.
