Add Account - Remove previous Tx history limitations

[gomesalexandre]

Overview

This issue is isolated to the "Add Account" feature only and is not related to the automagical accounts discovery.

Currently, we have some auto-"magical" accounts number discovery, which stops fetching when the current account has no Tx history.

That's one thing to use this as heuristics for discovery, but the issue here is the limitation is also here for manual "Add Account" functionality, without any rationale to limit users to do so.

Acceptance Criteria
