[JENKINS-49758] when passing in ref_spec with build parameters, the exact string "$REF_SPEC" is used rather then the value

To replicate:

1) create a job and pass in refspec as build parameter e.g. "$GIT_REFSPEC"

2) use the parameter "$GIT_REFSPEC" as the SCM configuration for git-plugin

3) The build will use the exact string "$GIT_REFSPEC" rather than the actual value of $GIT_REFSPEC for the fetch operation.

For example:

01:26:08 using GIT_SSH to set credentials Gerrit SSH Key

01:26:08 > /usr/bin/git fetch --no-tags --progress ssh://[github-project-url] $GIT_REFSPEC --depth=2

01:31:43 > /usr/bin/git config remote.origin.url ssh://[github-project-url] # timeout=10

01:31:43 > /usr/bin/git config --add remote.origin.fetch $GIT_REFSPEC # timeout=10

 

I believe the .toString in this line is causing this problem:
