Revise HTML patient export to omit measure information for portfolio users, thus allowing said users to export patient information across measures
Add sample measure as second measure test fixture. Added encounter information for an item from this new measure to record fixtures.
Add test to ensure that data from second measure is exported when exporting patient data as a portfolio user. Also modify existing export test to ensure this does not happen for non-portfolio users. Added a helper method for associating multiple measures with records.
Update other tests to factor in new measure fixture. Update new measure fixture with test HQMF id and HQMF set id to avoid clashing with data within measure exports zip file.
