test: gstreamer: Simplify elements' ownerships
In gstreamer, when elements are created, usually a floating [1]
reference is returned which simply means, there is no ownership
transfer (yet). 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.
