test: gstreamer_single_stream_test: Fix memory leak

The test hold a valid reference to convert0_ and sink0_ but
not released. This results in a memory leak and can be checked
via valgrind. Drop the references with test cleanup() virtual
function.

Valgrind log (glib and gst suppression files were used):
==345380== LEAK SUMMARY:
==345380==    definitely lost: 1,688 bytes in 2 blocks
==345380==    indirectly lost: 7,069 bytes in 42 blocks

The patch fixes the leaks reported by valgrind above to:
==348870== LEAK SUMMARY:
==348870==    definitely lost: 0 bytes in 0 blocks
==348870==    indirectly lost: 0 bytes in 0 blocks
