"Image and Title" template is not quite compatible with ACF

[Wiktor Walc]

The "Image and Title" template used to work in a bit specific way till 4.0.3. A template with an empty image has been inserted into the editing area. It was enough to double click on the image and set the URL in order to replace the empty <img> tag with a valid one.

After introducing ACF, the empty image is simply stripped, so it is somehow confusing that the image from a template does not appear at all.

I guess the most reasonable solution would be to insert a generic image instead of an empty tag, e.g. template1.gif that is provided with the templates plugin anyway. This way the default template would work even if one remove the samples folder (in case we wanted to use samples\assets\sample.jpg instead)
