[JENKINS-19276] Escape characters such as "\" for filepaths are being removed from variables loaded from properties file.

When triggering another build and loading a properties file, if you have Jenkin's variables with paths in them, the backslashes are removed for the variable.

Ex:

"ROOT_PATH=${WORKSPACE}
Results"

ROOT_PATH variable will appear with "C:jenkins_agentworkspace\Results"

and should appear as:

"C:\jenkins_agent\workspace\Results"
