When calling eZContentObjectTreeNode::fetch() by having $conditions argument set, one gets SQL error:

Query error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ANDezcontentobject_tree.contentobject_version='4' AND
ezc' at line 11.

$sqlCondition string concatenation is missing spaces.

Steps to reproduce

$node = eZContentObjectTreeNode::fetch($nodeID, false, true, array('contentobject_version' => $contentObjectVersion));
