        window.openDatabase() always fails for new databases when using WebKit nightly with Safari 4.0.5.  This is caused by a SecurityOrigin pointer comparison that I should have switched to be a hash comparison in r56293 [bug 34991].

        No new tests.  Requires testing on Safari on Windows.

        * storage/DatabaseTracker.cpp:
        (WebCore::DatabaseTracker::fullPathForDatabaseNoLock): Convert a pointer comparison to use SecurityOriginHash::hash() instead, and move it to the end of the clause for speed in the easy-out case.
