modify_reserved_instances ignores target_configuration.instance_type

[jbylund]

The ec2connection.modify_reserved_instances ignores an instance_type attribute in the target configuration.
To recreate purchase 2 x m3.medium reservations, then attempt to merge to 1 x m3.large.
I'm using
python: Python 2.7.8 (from ubuntu repos)
boto: 0dadce8
