Previously submitting a DELETE request to an issuable URL would be
enough to destroy it, but this should require human confirmation. We
now require that the `destroy_confirm` parameter is set to a truthy
value before this can complete.
In addition, we log a Sentry error if a deletion arrived without
confirmation.

This is to match our docs better and will also help a future issue.
Also made it possible for the description & title to be readable when JS is disabled
