It’s weird that this page changes when you click delete – it looks like
you’re going to a different page.
It should feel like you’re on the same page, just with the confirmation
message.
The problem we had before is that the rename form would `POST` to
`…/delete`, which would then delete the template instead of updating
its name.
We can fix this by explicitly setting the `action` attribute on the
rename form to always post to `…/manage`, even if the user is currently
looking at the `…/delete` page.
