Nick,
If you look at the code in the MyLocation widget you will notice that the LocateButton dijit is never really added to the HTML so you will never see the LocateButton dijits UI. WAB just uses the LocateButton in code so you could set the tooltip to whatever you want but you would never see it.
Also the correct code would be esriBundle.widgets.locateButton.locate.title (not sure where you got zoomLocateButton).
Here is what you can do to the MyLocation widget to get tooltips though:
