fix(kded): watch config also when known config is applied
Summary:
When a known config is applied the doApplyConfig with the Config wrapper
override is called. In this case we still want to activate config watching
like when a config from the ConfigPtr override is applied.
Otherwise we are not be able to detect a control change until the first time
a new config is applied.
Test Plan:
Started with rotation in manual mode. Switched in KCM only from manual to
automatic mode without changing anything else. With the patch the daemon
notices this change, without it not.
