title: Change google app engine name
body: <p>i cloned a working google app engine repo into my local env and got it to work.
  Later i decided i wanted to deploy to my own GAE app so i changed the name in app.yaml to the one in my newly created app.</p>
  
  <p>But then when launching it with the GoogleAppEngineLauncher i got this error:</p>
  
  <pre><code>BadRequestError: app "dev~bandtasticnews" cannot access app "dev~noticiashacker"'s data
  </code></pre>
  
  <p>The original name is noticiashacker and the new one is bandtasticnews, the cloned worked alright online but the dev is broken, i have to change the name on app.yaml to the original if i want it to launch locally and return it before deploying.</p>
  
  <p>There are no more lines on my code referencing the original name, i don't know why is it trying to retrieve it.</p>
  
  <p>UPDATE
  Here is the stack trace shown in the GoogleAppEngineLauncher logs</p>
