fix: default to External node

Embedded node with chrome.sockets is not ready yet.
Key blockers in js-ipfs need to be resolved first:
- /ipns/<fqdn>/ load fine
- sharded directories (e.g. wikipedia) load fine

We may also decide to keep External as default and just add a button
on Welcome screen that activates embedded note.
