* gles: Fix double frees
A recent update to the object wrapper classes (#1268) changed the
behavior of assigning to a wrapper, whereby the wrapped object is now
released upon assignment. A couple of tests were manually calling
clReleaseMemObject and then assigning `nullptr` to the wrapper,
resulting in the wrapper calling clReleaseMemObject on an object that
had already been destroyed.
