discv4: Fix Kademlia crash when trying to sync (#342) 
Fixes status-im/nim-eth#341, status-im/nimbus-eth1#489.

When using discv4 (Kademlia) to find peers, there is a crash after a few
minutes.  It occurs for most of us on Eth1 mainnet, and everyone on Ropsten.

The cause is `findNodes` being called twice in succession to the same peer,
within about 5 seconds of each other.  ("About" 5 seconds, because Chronos does
not guarantee to run the timeout branch at a particular time, due to queuing
and clock reading delays.)

Then `findNodes` sends a duplicate message to the peer and calls
`waitNeighbours` to listen for the reply.  There's already a `waitNeighbours`
callback in a shared table, so that function hits an assert failure.

Ignoring the assert would be wrong as it would break timeout logic, and sending
`FindNodes` twice in rapid succession also makes us a bad peer.

As a simple workaround, just skip `findNodes` in this state and return a fake
empty `Neighbours` reply.  This is a bit of a hack as `findNodes` should not be
called like this; there's a logic error at a higher level.  But it works.

Tested for about 4 days constant operation on Ropsten.  The crash which occured
every few minutes no longer occurs, and discv4 keeps working.

Add query proc and use this for recurrent queries 
This query proc is similar to the original (faulty) lookup proc.
But as we don't need to look for specific targets, it can be
used still as it gives a quicker and broader search resulting
in more nodes.
