Fix UNSUPPORTED_RESOURCE response in case HMI RC interface is not available

There was no checks that RC interface is not ready on HMI side so SDL sends
RC RPCs all time.
Following changes were done:
- Added IsInterfaceAvailable function to core service to check HMI interfaces availability
- Added check of RC interface availability in base command request
- Fixed unit tests due to changes in implementation
