re-arrange order of testing for panel or lab-test in histology & Dakolink labels - slightly easier to follow

RfC350L fix - DakoLink labels correctly skip unwanted tests * also fixed confusing data maps generated for histology & DakoLink labels - inconsistent use of test_name param (sometimes was actually field_label). Now uses lab_test object as hashref in data maps so downstream functions can consistently use correct key name (id, test_name, field_label, etc)
