Accounts data management (#1530)
* WIP accounts implementation

* Accounts datasore and changes to status mobile API

* Add library changes and method to update config

* Handle error after account selection

* Add two methods to start account to backend

* Use encrypted database for settings and add a service for them

* Resolve linter warning

* Bring back StartNode StopNode for tests

* Add sub accounts and get/save api

* Changes to accounts structure

* Login use root address and fetch necessary info from database

* Cover accounts store with tests

* Refactor in progress

* Initialize status keystore instance before starting ethereum node

* Rework library tests

* Resolve failures in private api test and send transaction test

* Pass pointer to initialized config to unmarshal

* Use multiaccounts/accounts naming consistently

Multiaccount is used as a login identifier
Account references an address and a key, if account is not watch-only.

* Add login timestamp stored in the database to accounts.Account object

* Add photo-path field for multiaccount struct

* Add multiaccoutns rpc with updateAccount method

Update to any other account that wasn't used for login will return an error

* Fix linter in services/accounts

* Select account before starting a node

* Save list of accounts on first login

* Pass account manager to accounts service to avoid selecting account before starting a node

* Add logs to login with save and regualr login
