fix: remove unreachable SSO-binding branch in networkCreateSeedphrase

networkCreateSeedphrase's only caller (NetworkCreate) guards entry on
networkCreate.AuthJwt == nil, so the "if AuthJwt provided, bind SSO too"
branch inside it could never execute -- dead code that also silently
swallowed a bind error via glog.Infof had it ever run, which would have
been a latent trap if the outer guard were ever loosened later.
