convert: avoid dirstate checks; add a test During a conversion, the dirstate contents are not consistent - there are files that may be missing from the dirstate and there may be files that shouldn't be in the dirstate. While this is not fixed, don't mark files as added - put them directly in state 'n'ormal.
