fix: complete pending queries when channel is closed

[derklaro]

Motivation

Currently, pending queries are not completed when the connection to a network component is lost, making them stall until the query timeout is reached.

Modification

Complete pending queries with a ClosedChannelException when a channel gets closed.

Result

No more stalling queries due to network components disconnecting.
