tests: Support list checks

Support string checks for JSON lists with the new __contains operator that
checks whether a string is contained within a list.

Example
    - JSON list: "ftp":{"reply":["Opening BINARY mode data connection for temp.txt (1164 bytes).","Transfer complete."], }
    - Check: ftp.reply.__contains: 'Transfer complete.'
