Previously, the filename ended up as part of the prefix explicitly, but now it needs to be explicitly included as input to token.

I thought that was already happening. Here is the token
```python
             token = tokenize(file_arg, group, decode_cf, mask_and_scale,
                               decode_times, concat_characters, decode_coords,
                               engine, chunks, drop_variables)
```

`file_arg` has the filename in it, no?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,229138906

@pwolfram: can you give any insight into what might be going on? 
This is an interesting trace from travis:

Does autoclose assume that the dask object names actually match the filenames?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,229138906
