`python manage.py check` helps us to find a lot of problems before
actually running the project itself / tests for it.
I think that one thing that we can also check statically is
`template_name` strings in different views that we have set-up in `urls`.
These templates can be found using regular Django machinery and help
finging issues sooner.
Basically, I expect:
```python
from django.views.generic import TemplateView
class MyView(TemplateView):
template_name = 'my.html'
```
to raise an error during `python manage.py check` if `my.html` cannot be
found with `TEMPLATE` loader settings. When `MyView` is present in
`urls.py` as:
```python
urlpatterns = [
path('/whatever', MyView.as_view(), name='whatever'),
]
```
What do others think?
