consolidated separate get_ontstanding_tests logic into single method call from get_single_request_data(); guest users see 'has lab tests pending' on summary page
moved _get_outstanding_tests() from C::Report to C::R::RecordHandler for sharing with printing and displaying report; moved all additional comments, errors, etc to common section at foot of body of printed report
added new function to require confirmation when reporting with outstanding test results; moved C::Report::_get_requested_tests() to C::Roles::ResultHandler; converted some template data objects to as_tree hashrefs to prevent db lookups when empty; fixed some tests to comply with new confirm_outstanding_results flag
bugfixes - new_request validation was broken by having 2 msg keys; fixed issue_diagnosis_revision_alert() in previous version caused test scripts to trigger messaging
