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.
