dirstate: invalidate on all exceptions
Previously, we would miss SystemExit, KeyboardInterrupt etc.
This "fix" on the bug tested in "test-largefiles-update.t" by preventing the
precisely tested situation to happens at all. However this reveal a similar bug
with a different timing.
I have not been able to deal with that pre-existing bug so far. So I updated the
test to point that out.
