dirstate: fix rebuild; add a test

If rebuild calls invalidate, it will just queue a (re)read of the dirstate
file, while what we really want is to empty the current state.

#!/bin/sh

mkdir a
cd a
hg init
echo foo > b
hg add b
hg ci -m "b" -d "1000000 0"

chmod -w .hg/store

cd ..

hg clone a b

chmod +w a/.hg/store # let test clean up

cd b
hg verify
