dlt-daemon: Continue to send log level / connection status even if error occurs (#61)

In previous, there was possibility that application could not get
notification from dlt-daemon due to wrong error handling.
(e.g.)
  1. App1, App2 and App3 register App/Context
  2. App2 crashes without unregistering App/Context
  3. Change default log level from DLT Viewer
     --> App1 can receive new default log level from dlt-daemon but App3 cannot.

This patch makes processing non-stop even if error occurs in below cases:
- While updating log level of all registered apps
- While updating default log level/ default trace status
- While updating connection status between dlt-daemon and dlt-client
