Fix dir-changed-to-file updates on clean workdir.

Workaround for dir-changed-to-file updates mentioned
in rev 7a64931e2d76 doesn't actually work since tests
introduced in mentioned changeset prevented dirstate
updates even if working directory updates succeded.

Make tests more relaxed for dirstate operations
not directly accessible from cli. See also issue660.

While here, move _dirs existance check from _decpath()
to _changepath() for unification.
