"Test" object has no attribute '_ctx'

This is probably related to the change in #24.

Using python 2.7.5 and Flask-Testing==0.4.1

tests.py

#!/usr/bin/env python2.7
import unittest

if __name__ == "__main__":
    suite = unittest.TestLoader().discover('tests')
    unittest.TextTestRunner(verbosity=2).run(suite)

./tests/testApi.py

from flask.ext.testing import TestCase

class TestApi(TestCase):

    def create_app(self):
        app = Flask(__name__)
        app.config['TESTING'] = True
        return app

    def test_server_is_up_and_running(self):
        pass

> ./tests.py

test_helloworld (testHelloWorld.TestHelloWorld) ... ok

You forget to import Flask but there was also a bug inside of the pre_setup and teardown.
Fixed with #48.
