remove test encryption on round application

[gravityblast]

if the round manager already sets the encrypted field on questions, we can remove this snippet added only to test the encryption:

    roundApplicationMetadata.applicationSchema.forEach((question) => {
      if (/email|cool/i.test(question.question.toLowerCase())) {
        // eslint-disable-next-line
        question.encrypted = true;
      }
    });
