Netlify-cms: Relation widget convert int to string

[mlasson]

Describe the bug

It seems that a recent update of the relation widget lost the ability to preserve the type of the relation.

In my case, I am using a relation to an integer and for some reason double quotes are added around the value (which turn into a string on the front-end side; I'm using jekyll, and in liquid when you compare 2 to "2" you get false, which breaks my site).

To Reproduce

Let say you have a category collection with a field of type int :

 - { label: 'Name', name: 'name', widget: 'number', valueType: 'int' }

and another collection with a field with a relation widget:

      - { 
         label: 'Category', 
         name: "category",
         widget: "relation", 
         collection: "categories",
         displayFields: [name],
         searchFields: [name],
         valueField: "name"
      }

Now in the front matter block I get :

category: "4"

Expected behavior

When I'm saving/updating an object I'm expecting to find

category: 4

in the front matter block.

Applicable Versions:

netlify-cms-app 2.12.12
bootstrap.js:83 netlify-cms-core 2.26.0
index.js:27 netlify-cms 2.10.48

Note:

I fixed my website simply by turning the integer fields into string fields, so the issue stopped being one for me, but I would not be surprised if some other users hit the same problem.

Thanks @mlasson, this is probably since we added string template support for the widget.
