test: move test-shadow-realm-gc.js to known_issues

There is actually a leak. The test doesn't exercise the right
path to create a substantial enough object graph (e.g.
accessing something that results in the loading of a binding).
This does something more complicated in the test and moves it
to known_issues until we find a fix.
