[JENKINS-10779] Non-existing parameters are not empty but replaced with parameter name

Version

Setup

Project1 is set up to trigger parameterized build on Project2 with parameter
```
SOURCE_JOB_NAME=$JOB_NAME
```
Project2 is set up to trigger parameterized build on Project3 with parameter
```
SOURCE_JOB_NAME=$SOURCE_JOB_NAME
```

Project3 has one build command:

echo Source project name is \"$SOURCE_JOB_NAME\"

Problem
When building Project1, Project3 prints the following as expected:

Source project name is "Project1"

But, when manually triggering Project2, then Project3 prints:

Source project name is "$SOURCE_JOB_NAME"

I would expect it to print:

Source project name is ""

Which is the normal behaviour when playing around with variables in sh.
