libp2p bug: invalid p2p address returned in call to listenAddresses() when intializing libp2p host with localhost

[chaitanyaprem]

Describe the bug
In peermanager test code, when extracting multiaddresses for host created using localhost address go-libp2p's call to fetch listen addresses via h.Network().ListenAddresses() seems to be returning an empty p2p-circuit address which has lead to write conditional code.

Refer #787 (comment)

Expected behavior
Call to fetch network listen addresses should return only valid addresses.

Closing as discussed on 02/13 go-waku PM call. This issue is already handled in the code.
