        Bug 19822: REGRESSION (r30243): setting location.hash to "#" causes a reload
        <https://bugs.webkit.org/show_bug.cgi?id=19822>

        Change JSLocation::setHash() to not schedule navigation in the case
        where the old fragment is the null String and the new fragment is an
        empty String.

        WebCore:

        * bindings/js/JSLocationCustom.cpp:
        (WebCore::JSLocation::setHash):
