Fixed a bug with dirty node handling.

We used to share a single instance of ArtifactNestedSetValue among all the
NodeEntry for ArtifactNestedSetKey. That's a problem for propagating the dirty
status along the reversed dependency edges (because of the SkyValue remains the
same, the propagation is stopped).
