title: create-admin error: There in no appbuilder var on your package, you can use appbuilder parameter to config
body: <p>I am facing issue with the command: fabmanager create-admin
  Here is a sequence of steps I performed:</p>
  
  <p>I followed all the installation steps on my Windows 10 machine to install flask_appbuilder. Then I downloaded the skeleton app using the command : "fabmanager create-app". But when i issue the command: "fabmanager create-admin" from the newly created skeleton app dir, it throws the error:</p>
  
  <p>"There in no appbuilder var on your package, you can use appbuilder parameter to config".</p>
  
  <p>I checked the app/<strong>init</strong>.py file, it does contain the appbuilder var. Here is dump of that file:</p>
  
  <pre><code>import logging
  from flask import Flask
  from flask_appbuilder import SQLA, AppBuilder
  
  logging.basicConfig(format='%(asctime)s:%(levelname)s:%(name)s:%(message)s')
  logging.getLogger().setLevel(logging.DEBUG)
  
  app = Flask(__name__)
  app.config.from_object('config')
  db = SQLA(app)
  appbuilder = AppBuilder(app, db.session)
  
  from app import views
  </code></pre>
  
  <p>I tried issuing the same command with admin rights, but no success.
  As per the documentation, if we try to use a different name (other that appbuilder), we can make use of --appbuilder option to configure that, but in my case I am not doing any such thing.</p>
  
  <p>Please suggest.</p>
