AI 144661: Fix #175030. Preserve the zoom factor during refresh. Remove the code change in FrameLoader.cpp which was to preserve the zoom factor when we first did layout. Now we only use the initialZoomScale if it is a standard load. If it is history load, restoreScale() should be called before didFirstLayout(), in the other cases, like reload, refresh, replace, we don't change the zoom factor.
