android: add misssing error codes to stackResultToStr()
The OC_STACK_UNAUTHORIZED_REQ error code and some others were missing in
the method for translating them into strings.
Without this patch it resulted in this exception:
org.iotivity.base.OcException: stack error in onObserveCallback JNI_INVALID_VALUE
