Subject: [PATCH] 0033436: Data Exchange, DE_Wrapper -
 DEXCAFCascade_ConfigurationNode::BuildProvider() not initialize provider

Pass pointer to DEXCAFCascade_ConfigurationNode to DEXCAFCascade_Provider;
Remove forcible manual reset of Provider's node in DE_Wrapper::FindProvider() to verify that all specializations of configuration node work properly without necessity of workarounds.
