Make client asynchronous base handler only attemp to dispatch response packets, and raise if it is not an expected response.
Add a method on Packet class to determine if it's a response.

table/IDs were gathered before, wait for at least one storage node and use the
first to create the initial partition table.
A timeout is left to act as it was done before, to preserve automatic startup in
tests, will be removed latter.

Make handleAnswerPrimaryMaster, handleRequestNodeIdentification and handleAskPrimaryMaster resilient to connection loss. As they are involved in question-response exchanges during election on connections which will get dropped as soon as a master arises, they must check if the connection is still opened before trying to send.
Note: the connection might get closed anyway during the actual send, but this is handled separately already. The problem we fix here emerged because of more tedious checkings in Connection's ask & answer methods.
