Empty enums

[anttileppa]

After Wordpress 4.7 upgrade empty enums appeared into template POST parameters in several enpoints (Page, Post):

e.g.:

{  
  "name":"template",
  "type":"string",
  "in":"formData",
  "description":"Teematiedosto joka n\u00e4ytt\u00e4\u00e4 kohteen.",
  "enum":[
    ""
  ]
}

Is that by design I wonder?
I see plenty of other template variables that have an enum list...

I'm not sure what should be here though?

I have also come across this issue. Also I my swagger UI would not display this because of null values. I have written a small fix, maybe you want to add this.
