Fix gstreamer elements references
In backend-fs2, the create_src will unref the src after it's done with
it, if we simply return the created source, it will segfault.
The issue never happened before because every source so far also has
the UNIQUE flag, which causes it to go in a different branch of the
code which does ref the element and add it to the bin.

Refs #16315
