routing: if the graph has never been pruned, prune with current height

Browse Source 
In this commit we ensure that if this is the first time that the
ChannelRouter is starting, then we set the pruned height+hash to the
current best height. Otherwise, it’s possible that we attempt to update
the filter with a 0 prune height, which will restart a historical
rescan unnecessarily.
