Hmm, somehow I missed that failure. Easy to fix, just added a HTLC to make update_fee work. |

Sending update_fee immediately after channel establishment seems to upset LND, so work around it by deferring it. The reason we increase the fee after establishment is because now we might need to close the channel in a hurry due to htlcs, but until there are htlcs that's unnecessary.
