This change makes _save_device_metadata only query the database for the instance BlockDeviceMappingList if there are block device mappings in the block_device_info dict. If there are none, then there is no point in making the extra useless query to the database. A TODO is left in the code since this could be further optimized if the DriverVolumeBlockDevice object would proxy the 'tag' attribute from it's underlying BlockDeviceMapping object, but that is a bigger change saved for another time. The existing unit test is fixed up and another unit test is added to validate that we don't query the database if there are no block device mappings to process.
