CLI - known account doesn't work in CLI

Here #238 (comment 180150) is described how known accounts works in TUI.

I think there is no need of possibility to manage known accounts list in the CLI, but it should work in the same way in case on working account, tracked/watched accounts and receivers of the operations.

Now it doesn't work like this:

1. Working and watched accounts are not known accounts

2. In CLI it should be possible to add or remove an account name to/from known accounts list.

3. Receiver of the transfer is not added to known accounts list - it is result of issue #307 (closed)
