Add CallLog provider loggging to check for app-ops denial.

If an app-ops denial occurs while inserting into the call log in Telecom
its not entirely obvious why call log entries are not being added.
Adding a log message to make it more clear when call log insertion is
silently failing so that this can be root-caused easier in the future.

Test: Compile, manual test to check for log messages
