fix: allow local node to connect without HTTP

[antazoey]

What I did

a miss, unable to use IPC or WS alone without HTTP

How I did it

make http uri optional in a helper method

How to verify it

node:
  ethereum:
    local:
      uri: $HOME/.ape/node/geth.ipc

crazy, this even works with wss on mainnet:

INFO: Connecting to existing Geth node at wss://eth-mainnet.g.alchemy.com/[hidden].

In [1]: 

edit, somehow even get_block work! But it already has the txns filled out, a bit different.

yeah you can do those methods w/ websockets, just not preferrable
