[emms-help] emms-stream constantly adds metadata to urls

[Konstantin Reich]

Hi,

Any url added after a stream from the EMMS Streams interface has the stream 
metadata. 
I think it is a bug.

One can reproduce it with the following steps.

1. (emms-streams)
2. Choose any stream
3. The stream has some metadata which is written in emms-stream-last-stream.
4. add url through emms-add-url.
5. The url has the same metadata.

I can suggest the following correction:
