UUID composer.json caused composer_manager update to fail

The composer.json file in the UUID module directory causes an incompatibility with the the composer_manager module.

When the UUID module is enabled, its composer.json is included when the composer_manager module builds the site's aggregate composer.json.

Trying to run the drush command "composer-manager update" results in the following error:
