-----------
window.open() with noopener should not always return null
https://bugs.webkit.org/show_bug.cgi?id=322591
Reviewed by Chris Dumez.
The name lookup in "the rules for choosing a navigable" ignores noopener, so
window.open() can reuse an existing navigable when noopener is set. Two things
were wrong when it did: the reused navigable got its opener set to the caller,
and _self returned null instead of that navigable. _parent and _top were already
correct, as open() resolves them without reaching createWindow().
