cmd/tendermint/commands/lite: add tcp scheme to address URLs (#1297)

Noticed while investigating
https://github.com/tendermint/tendermint/issues/970

As reported by @zramsay, we'd get the warning
from tendermint/rpc/lib because we were passing in
scheme-less addresses, so by default use "tcp".

Also by default, "node" (nodeAddr) has been set to:
  "tcp://localhost:46657"
instead of the bare:
  "localhost:46657"

This change is just to clean up such warnings as
they spuriously would spook users for a package "lite"
that claims to be secure.
