Disable default accounts

[Giszmo]

Currently, the app loads a bunch of default accounts. This script should only be executed if the user clicks on a button to do so. This feature is a debug feature anyway but for debugging it's still helpful, so it should not be removed completely yet.

The reason why I want it to be removed is to make links to events and profiles load quicker for users that don't have a saturated local db yet. I want to share for example https://chat.nostr.info/event/435c44c5b5dd8abceefe5f4ac176165618732178f4864d822979153a3fe9ad7f/ on Telegram but in its current state that's an embarrassment and whoever clicked it will never come back.

This can be split in two parts:

• Remove default accounts
• Console.log() what to run on the dev console to trigger adding them. No button needed.

The default accounts are confusing users that now increasingly show interest in using this client, too.
