Subject: [PATCH] ozi: don't deinit a write stream if we don't have one.

We can get into close() with a null stream_ TextStream. I think it has to do with ozi_openfile() reopening a file with a new name to match an extension of a certain type so it's renaming a file that hasn't been written. See issue #646
