Issue1790: dirstate entry locked into unset if file mtime is set into
the future
Prepare test repo:
$ hg init u
$ cd u
$ echo a > a
$ hg add
adding a
$ hg ci -m1
Set mtime of a into the future:
$ touch -t 203101011200 a
Status must not set a's entry to unset (issue1790):
$ hg status
$ hg debugstate
n 644 2 2031-01-01 12:00:00 a
Test modulo storage/comparison of absurd dates:

Transaction compatibility
-------------------------
The transaction preserves the dirstate.
We should make sure all of it (docket + data) is preserved
