test: gstreamer: Fix the destructor of GstreamerTest base class

The destructor tried to check if pipeline_ is a parent of libcameraSrc_.
This was needed to be checked as if it is, cleanup of libcameraSrc_
would be handled by pipeline itself.

Since, the destructor can be called anytime, even when pipeline_ hasn't
been created, the use of pipeline_ to check if libcameraSrc_ has an
ancestor as pipeline_ caused a segmentation fault.
