funding: don't case to a net.TCPAddr to support tor stream isolation 

In this commit, we fix an existing bug in the funding manager, that can
be triggered if the user is connecting to a node over Tor, and then
attempts to open a channel. An existing fix was added for the case that
the receiving node established the channel, but this now makes that case
symmetric.
