Do not require an account id for importing addresses

[KtorZ]

#258

Overview

• [ ] I have remove the 'accountIndex' from the import-address endpoint

Comments

Actually, we were sort-of ignoring it already and the endpoint was misleading. Cardano addresses embed their corresponding account index inside them, therefore, when importing addresses, we only care about the root master key (and therefore, the root id). The account ix comes from the address anyway

@KtorZ perhaps you might want to update also ->

• https://input-output-hk.github.io/cardano-wallet/#section/Common-Use-Cases/Importing-(Unused)-Addresses-From-a-Previous-Node-(or-Version)
• https://input-output-hk.github.io/cardano-wallet/#tag/Addresses%2Fpaths%2F~1api~1v1~1wallets~1%7BwalletId%7D~1accounts~1%7BaccountId%7D~1addresses%2Fpost

(not sure, the latter will update automatically?)

[KtorZ]

Indeed. And I'll also update the manual tests instruction / scripts. Thinking about getting yours merged before.

[piotr-iohk]

No probs, I can update manual tests under #319.

[KtorZ]

Updated manual tests, API layout and Swagger documentation :+1:

:+1: Feel free to merge. I'll add tests in #319 on the top of it if that's ok.
