* WebProcess/WebPage/mac/ServicesOverlayController.mm:
(WebKit::ServicesOverlayController::drawSelectionHighlight):
We can't early return in the rich-content-but-no-rich-services case
if we have telephone numbers in the selection, because we want to offer
them up in the combined menu.

* UIProcess/mac/WebContextMenuProxyMac.mm:
If we end up with no menu, because there were no services available,
make a fresh one that we can fill with combined telephone number items.
