array_flip error during doing rebuid of the feature with nodes

Every time when i'm trying to revert\rebuild a feature with node on a fresh and clean drupal i got an error
Warning: array_flip() [function.array-flip]: Can only flip STRING and INTEGER values! in DrupalDefaultEntityController->load() (line 178 of /var/www/staging/inuits-eu/includes/entity.inc).

Why it happen:
During revert\rebiuld the uuid_features module tries to get a nid of the each node by uuid from DB, then do node_load.
If there is no such node in the DB (e.g.: clean installationthe) MySQL query will return FALSE, and it will become as $nid value.

/* uuid_features/inclides/uuid_node.features.inc, line 127 */
      // Find the matching UUID, with a fresh cache.
      $nid = uuid_node_find($node->uuid);
      $existing = node_load($nid, NULL, TRUE);

The $nid should be string or integer, but not bool.

Here is the patch, which will fix the problem.
