Self-managed CS implementation continued.

As I wrote the CTS tests, I ran into a few cases that needed to be handled
properly.

1. When attempting to register a self-managed CS, if the caller has included
property call provider, sim sub, or connection mgr, we throw a security
exception.
2. Added implementation for the wait-on-handlers telecom command.
3. Prevent logging of self-managed calls.
