/**
 * @assertion HttpHeaders defaultResponseHeaders
 * Default set of headers added to all response objects.
 *
 * By default the following headers are in this set:
 *
 *  Content-Type: text/plain; charset=utf-8
 *  X-Frame-Options: SAMEORIGIN
 *  X-Content-Type-Options: nosniff
 *  X-XSS-Protection: 1; mode=block
 *
 * If the Server header is added here and the serverHeader is set as well then
 * the value of serverHeader takes precedence.
 * @description Checks that some headers can be added and removed using this
 * property
