FacesContext#setViewRoot() should not clear RENDERED_RESOURCE_DEPENDENCIES during a non-@all partial request

[BalusC]

Currently, FacesContext#setViewRoot() calls RequestStateManager#clearAttributesOnChangeOfView() when a view has been changed. However, when PartialViewContext#isAjaxRequest() returns true and PartialViewContext#isRenderAll() returns false, then it should not clear context attribute RENDERED_RESOURCE_DEPENDENCIES as it will otherwise cause ResourceHandler#isResourceRendered() to falsely return false when it was true on the initial view.
