[jumbo] One kInvalidId constant should be enough.

Jumbo compilation in components/sync broke when a kInvalidId
clone appeared with the same name. This build unbreaking patch
renames it to kInvalidNodeId. A longer term fix is probably to
move the constant to modules/sync/base or another shared location.
