    Description

      When setting an environment variable equal to a blank string it comes back a the literal string of `null` instead of being a blank string

      Steps to reproduce:

      1. Create a new pipeline job with the following definition:
        pipeline {
            agent any
            environment {
                VERSION_SUFFIX = ''
            }
            stages {
                stage("test") {
                    steps{
                        echo "env.VERSION_SUFFIX = ${env.VERSION_SUFFIX}"
                    }
                }
            }
        }
        
      1. Run said pipeline
      2. Observe the output is `
        env.VERSION_SUFFIX = null

      Expected result:

      Normally I would expect it to just be a blank string or nothing there
