evolve: fix the dirstate after setting parents with dirty wdir (issue5930)
Before this patch, during an interrupted evolve it can be confused
about copies. This patch fix the dirstate when parents are changed
using dirstate.setparents() with a dirty wdir.
Changes in test file reflect the fixed behaviour.
Testing `hg stack` on complex cases when we have multiple successors because of
divergence, split etc.
