The SimpleDateFormat in QueryBuilderImpl formats midnight as T12:00:00.000Z

[Martin Wink]

In org.springframework.social.google.api.query.impl.QueryBuilderImpl the dateFormatter SimpleDateFormat is incorrect.
It specifies the hours as "hh" which is the 12 hour format, so midnight is formatted as "12".
Changing it to "HH" corrects it, so midnight appears as "T00:00:00.000Z"
