added selection by lab tests to PCR worklists; reinstated collapsing multiple requests in PCR worklist (retained split on specimen); bugfix to PCR status - only require new, not everything < complete; force CHIM DNA extraction requests to 3 rows

molecular worklists split specimen at request selection stage not final worksheet display - to allow individual specimens to be selected per request

bugfix - extraction worksheets not sorting by year & request number
