Insert transaction ID into AssetXferUploader constructor rather than at UploadAsset() to prevent item creation failure when NewInventoryItem thread reachs the object first. 

This was preventing the previous race condition fix in 4fc0cfb from actually working.
This commit also removes some of the pointless transaction id checks - these conditions are already being enforced in AgentAssetsTransactions.
