fix: cae1bbf2536b - expression errors not setting result properly Rather than setting 'result' in renderContext, I was wrirting the output directly, but was stil falling through to where result would be used. This caused email to be sent to the admin and when test_mailgw was called the mail-test.log was somehow created and caused the test there to fail. Fixed renderContext to use result variable and output contents of mail-test.log to make debugging easier. This should fix CI failure.
