Make EntityDeleteMixin.delete deal with HTTP 204s

An HTTP 204 response indicates that a request has been processed but no content
is being returned. When this happens, any attempt to decode the JSON in a
response will fail, because no content is available to decode that content. Make
`EntityDeleteMixin.delete` deal with this case. This fixes a test failure.
