A bug was found whereby the body of a template was not being shown in the
on the page when returning to edit an existing template. This bug was caused
by renaming the field in some places, but not in the `Form` class.
This bug has since been fixed, but this commit adds a test to make sure that it
doesn’t happen again.
WTForms sets the `id` of a `textarea` element to the variable name to which the
form control is assigned.
This conflicts with the page container, which is styled by targeting `#content`.

This is a link not a button because:
- it’s less prominent—delete is an infrequent action
- it’s a two-step process, and only the second part changes any data (so it has
a button)
