Closed Issue: [2.3] includereferencedprojects need to parse id token before adding the nuspec dependency [3121]

1. classlibrary3 references classlibrary51.
2. Classlibrary51 has nuspec file with version token
3. nuget pack -includereferencedprojects -verbosity detailed

Actual:
NuGet.CommandLineException: Error occurred when processing file ClassLibrary47\ClassLibrary51\ClassLibra
ry51.nuspec': '$version$' is not a valid version string. ---> System.ArgumentExc
eption: '$version$' is not a valid version string.

Expected:
it should replace id tokens before trying to add the package dependency.
Comments: Verified in the nightly build id token is not getting replaced correctly.
