fix: allow working without connection

[antazoey]

What I did

Bug where you needed to be connected to a provider to see accounts, causing ape ledger list to not work.
This was a regression from the change in ape but somehow did not fail the tests?? I am not sure how.

How I did it

• Grab the ethereum ecosystem manually.
• Also created this issue as a future: Support accounts on different networks and ecosystems #23

How to verify it

Tests pass again.
Can use ape ledger list
