fixed M::Result::update_results_summary() to reset history actions before running transaction to correct auto-incrementing 'reported' action for bcr-abl uploads; simplified generate_new_password() method
patched cgiapp_prerun to accept skip_redirect flag created during reset password using emailed link, so destination=change_password happens without re-direct; changed M::Roles::ResultsUpdate::history_params attr from lazy_build to std method - was not appropriate to have lazy_build & 'clear' for method called from within loop
