fix: webrtc NoValidAddressesError error

[dozyio]

Description

Webrtc connections can fail to during upgrade from circuit-relay connect with NoValidAddressesError - seems that this is due to coalesced dials not picking up new multiaddrs if they are added during an in-flight connection attempt. That will require a larger fix but this patch helps resolve the issue at the current call site where NoValidAddressesError is thrown.
