salesforce_object_map entries for nodes not removed upon node deletion

Hello,

The code to delete the object map when a node is deleted is not functioning because :

• It passes the wrong type to salesforce_api_delete_object_map. The type for all nodes is
  'node', while it passes 'node_[node_type]' ;
• It passes the node's uid instead of the node's nid.

Thanks,
Anselm

Ps. Issue was originally entitled 'Mismatched values for drupal_type in salesforce_object_map table' as I wasn't sure what the issue was - but further investigation convinced me this code was buggy.
