replaces #708

It looks like when we switched to using QueryFilters to remove relayed peers or other undesirables from our queries we ended up effecting FindPeer because FindPeer isn't treated like a normal put/get but as an "accidental" extension of a normal query.

See #584 for more info on the specialness of FindPeer

… dialed as part of the query under the queryfilter
When performing queries query the next peer if it happens to match
the target even if it would normally be excluded by the queryfilter.

This is meant for fixing FindPeer, but for ease of implementation
is applying more broadly to queries like GetClosestPeers as well.

This will "fix" the issue, but we should probably return the target peer some other way.

Not sure if it's worth fixing separately from #584 though. It'd be more "correct" to have a special path through the query logic for FindPeer (e.g. even just a field in the query struct isFindPeer), but not sure whether it's worth the bother/added code complexity.
