localrepo: filter unknown nodes from the phasecache on destroyed

When commit is followed by strip (qrefresh), phasecache contains nodes that were
removed from the changelog. Since phasecache is filecached with .hg/store/phaseroots
which doesn't change as a result of stripping, we have to filter it manually.

If we don't write it immediately, the next time it is read from disk the nodes
will be filtered again. That's what happened before, but there's no reason not
to write it immediately.

The change in test-keyword.t is caused by the above.

'''command to display child changesets (DEPRECATED)

This extension is deprecated. You should use :hg:`log -r
