This is not fixed:
Use-case: creating a package with dlls in the lib folder but you want neither one referenced in the target project by default.
Workaround (easiest): add a single reference in the <references> tag that is not a dll (like a .js file). This will be omitted when adding references but since your <references> is non-empty, no dll references will be added.
Suggested solution: take an empty <references /> declaration literally and don't add any references from lib automatically.
