Use correct path to do attribute check. Refs #777

The problem was the "convert" link on the list analysis page would run a query and display all fields for that class instead of just the ones that were configured.

The method of interest, `getDefaultViewForClass()`, is used when we have a query and a type but no view list. We want to get the view list set in the config file. This method is used a great deal, e.g. on the list analysis page. 

The problem is the code was using the full path, e.g. `Gene.proteins.accession` instead of `Protein.accession` and (for some reason) the code discards non-attributes. Normally, e.g. for list analysis page, this isn't a problem. But since these are conversion templates, it was discarding all fields configured therefore using all fields -- which is the default behaviour when there is no config.
