Add new routine to check waiting countsubmit/tizen_unified/20170308.100404submit/tizen/20161220.104958accepted/tizen/wearable/20161220.223751accepted/tizen/unified/20170309.031621accepted/tizen/tv/20161220.223723accepted/tizen/mobile/20161220.223649accepted/tizen/ivi/20161220.223818accepted/tizen/common/20161220.191011

If some API's return value is come lately from muse server after waiting timeout, api_activating can be true.
Then, previous return value is returned if same API is called.
This patch resolves it.
