getPagePrefix

[jonwinton]

Might consider adding as it's a part of Amphora's references module that is used in publish chains sometimes:

/**
 * Get the prefix of a page like 'some-domain.com/some-path/_pages/' with the page id.
 *
 * @param {string} uri
 * @returns {string}
 */
function getPagePrefix(uri) {
  return uri.substr(0, uri.indexOf('/_pages/'));
}

getPrefix handles page uris
