uncommit: fix the dirstate handling in `uncommit -i` This patch fixes the dirstate handling after `hg uncommit --interactive`. This patch is bit verbose about the logic and efforts are not put to plug the logic into existing logic as it's easier to understand like this. Plugging this into non-interactive logic deserves a separate patch.

Examining the file
------------------
XXX: there is a bug in interactive selection as it is not letting to examine the
file. Tried with curses too. In the curses UI, if you just unselect the hunks
and the not file mod thing at the top, it will show the same "nothing unselected
to uncommit" message which is a bug in interactive selection.
