Validates whether this template will work on site pages.
In order for a template `A` to work on a page from site `A` the

* template A needs to be assigned to site A
* content from template A needs to be a valid django template code
* other templates used in template A (with `include`/`extend`/etc.

* other templates used should not create infinite recursive calls(
