network: handle empty wsPeer supplied to transaction handler

[algorandskiy]

Summary

There is a race between pubsub new peer discovery and wsPeer registration:

Suggested fix is to use gsPeer temporary type good enough for tx handler, and delay its resolution to wsPeer.

Test Plan

Added a test confirming a closer set by ERL to a temporary peer is propagated to a wsPeer.

Looking for opinions on a current delayed lookup via OnClose, or adding a p2p event listener and a permanent background goroutine for remapping pending connected peers to wsPeers (peers supporting our custom proto).

Replaced with #6195 after @cce pointed out we do not have ERL for p2p/pubsub case so no extra OnClose handling needed.
