Fix logs are placed in std output during CLI tests
There was an issue with CLI tests - all logs were visible in the result.output. So it was not like the real usage, because logs are not placed in stdout in real user scenario. This MR fixes that by disabling stdout/stderr handlers in CLI tests.
Also setting proper logger configuration for unit and TUI tests.
Requires: !553 (merged)
