The value of the "id" property needs to be unique. You will see the following error if you view the console of your background page:

contextMenus.create: Cannot create item with duplicate id google

Do not call chrome.contextMenus.create for each context, but assign the list of contexts to the contexts key:

chrome.runtime.onInstalled.addListener(function() {
  var contexts = ["page","selection","link","editable"];
  var title = "Google Search";
  chrome.contextMenus.create({
    "title": title,
    "contexts": contexts,
    "id": "google"
  });
  // ...
});
