Do not attempt anymore to run Allure test report upload script on same directory of previous launch. It was useless (since Allure retries are evaluated within a tester execution) and confusing as the test job ids don't match
- Use find -path option as we search for a path and not a file/directory. Keeping -name would fait silently in case of a retry/amend
- Fixed several syntax errors (escape sequences)
