When editing an email template with the wysiwyg,
the `<` and `>` operators are automatically converted
to `<` and `>`, even for the Jinja2 conditions,
therefore breaking these conditions, and the render
of the email templates.
We avoid to use these operators in the email
template, so users can customize the notification
email template without having an advanced
knowledge on how to edit an email template containing
Jinja2 code.
Besides, the line return at the end of the email template,
just after the `% endif`,
is done on purpose as well: the wysiwyg adds automatically,
at the time of this revision,
`<p></p>` at the end of the email template source, but
this cannot be added on the same line than `% endif`,
otherwise this is considered as Jinja2 code, and it's not.
