Disconnect from the Mongo server.

Don't call the Mongo->close() method. The driver documentation states this should not
be necessary since it auto disconnects when out of scope.
With version 1.2.7, when using replica sets, close() can cause a segmentation fault.

@return boolean True
Disconnect from the Mongo server .
