fix(tests): Fix local test failing for account ID checks

[lucashuy]

Which issue(s) does this change fix?

None

Why is this change necessary?

A recent change made to the local command behaviour causes some of the integration tests to fail. This is due to the local integration tests never expecting there to be an actual valid account ID, however this is no longer the case.

How does it address the issue?

Checks if the account ID looks and smells like an account ID, instead of checking for an exact value.

What side effects does this change have?
