Settings: QuierHours service: call with qualified user and introduce controller

This commit fixes 2 issues:

1. Call the service with a qualified user.

2. Complete overwork of the handling. Currently the SmsCallHellper is doing
   way to much work. Especially when time change broadcasts trigger the service
   update. Which ended in certain cases to a complete system overload.
   To fix it we use now a single tone controller to take care of this all
