REPL tells to run `configure` after `setqr dcaccount:`

[link2xt]

When running REPL and executing setqr dcaccount:ci-chatmail.testrun.org as the first command, repl runs configuration and in the end says "Config set from QR code, you can now call 'configure'".

But the account at this point is already configured:

> get configured
configured=Ok(Some("1"))

This is true for version 2.27.0. I think at some point setqr did only set addr and mail_pw.

We should at least remove this line from the REPL, but also maybe update the documentation so this behavior of set_config_from_qr is expected.
