Once can simply check for NULL and return through an error path, without bothering to clean up. Hence, g_autoptr is not much of help here. If the NULL checks have been passed successfully, elements are ready to use. However, we must claim ownership/reference it before using them via g_object_ref_sink(). This patch build upon this principle and removes the g_autoptr from gstreamer test base class (gstreamer_test.cpp) whereever necessary to tide up the code.
