Swap order of merged params to fix sponsor select view The sponsor select view (in 'create new program') was showing the wrong information (and also using the wrong list template) because the order in which the params were merged was wrong way around. This fixes that and at the same time fixes the 'instruction_text' attribute, which should be named 'list_description' instead. At the same time we lookup and set Sponsor as the scope of the newly created program. Patch by: Sverre Rabbelier
