Fix issue about GHashtable and GListsubmit/tizen_3.0/20161117.022446accepted/tizen/3.0/wearable/20161118.003808accepted/tizen/3.0/tv/20161118.003746accepted/tizen/3.0/mobile/20161118.003726accepted/tizen/3.0/ivi/20161118.003828accepted/tizen/3.0/common/20161118.192937
- The issue mat arise if GList is used for the value of GHashtable,
If the head list of GList is deleted, GHashtable will not be able to
find GList.
The problem is solved by replacing the corresponding list with GHashTable.
