bug 1580391 shows that .contentWindow can be null when it shouldn't be.
The iframe element there is in DOM all the time, but at some point
.contentWindow becomes null.

The other cases when ClearWindowProxy is called seem to be fine.
It is the Unlink case which was causing null .contentWindow with test_mozfiledataurl.html

Fixes bug 1580391 and backs out bug 1581004
