Included/Updated Unit Test Cases for Meetup API. When Events API is
called, the response is list/array of results(EventResults) object not a
list of Events.

Now able to test using Spring Test module. The accessToken is obtained
when executed the QuickStart sample modified to store the UserConnection
values in Database instead of Memory.
Modified to store UserConnection Data in MYSQL Database, so it helped me
to retrieve the accessToken and perform Unit test in
spring-social-meetup project only.
