When multiple clients request qseecom to load an application, an app id is assigned. If the request is to load an app that already exists in qsee, the app id should return to the qseecom library. Returning the app id was done in the qseecom_load_app() but not done in the qseecom_query_app_loaded(). This change fixes the issue when multiple clients request to load the same app in qsee.
