git-prompt: improve cherry-pick/revert detection
If the user commits or resets a conflict resolution in the middle of a
sequence of cherry-picks or reverts then CHERRY_PICK_HEAD/REVERT_HEAD
will be removed and so in the absence of those files we need to check
.git/sequencer/todo to see if there is a cherry-pick or revert in
progress.
