This modifies the `genMacaroons` logic to indepently check for each of
the three default macaroons (admin, readonly, invoice) and generate
whichever are missing. Previously, this was an all or nothing routine.
In other words, either all three didn't exist on disk and all three are
created, or no macaroons are created. Although that works for the first
run of a new node, it can result in inconsistent states if only one or
two of the macaroons is deleted.

In this commit, we an existing gap in our rebroadcast handling logic. As
is, if we're trying to sweep a transaction and a conflicting transaction
is mined (timeout lands on chain, anchor swept), then we'll continue to
try to rebroadcast the tx in the background.
To resolve this, we give the sweeper a new closure function that it can
use to mark conflicted transactions as no longer requiring rebroadcast.
In this commit, we increase the default CTLV value to 80 blocks.
Initially this was set to 144 blocks in the early days, but then was
lowered to 40 blocks as the lnd implementation matured. By setting this
to a higher value, we increase the safety window (MTTR) when it comes to
node downtime, and also add some buffer room around time locks which may
become more stressed in the future assuming the current mempool load
remains persistent.
In this commit, a bug is fixed in the funding manager that could result
in the funding process erroring out if the persisted initial forwarding
policy is not found. This could occur if a node restarts after opening a
channel that is not yet fully confirmed and also upgrades their node
from a pre-0.16 version to 0.16 since the values are only expected to be
persisted after 0.16.
In this commit, a small migration is added to the watchtower client DB
to ensure that there is an entry in the towerID-to-sessionID index for
all towers in the db regardless of if they have sessions or not. This is
required as a follow up to migration 1 since that migration only created
entries in the index for towers that had associated sessions which would
lead to "tower not found" errors on start up.
