What happened?

I tried creating a custom command, that talks to mopidy itself to clear the tracklist.

I did this by telling iris to send a request to http://localhost:6680/mopidy/rpc with the headers content-type: application/json and the following body:
{"jsonrpc": "2.0", "id": 1, "method": "core.tracklist.clear"}

When trying this command, iris sends the following body instead:
"{\"jsonrpc\": \"2.0\", \"id\": 1, \"method\": \"core.tracklist.clear\"}"

This seems like iris is sserializing the string, instead of directly passing it to the request. This could be because of these lines in core.py.
As a temporary fix, I've removed these lines in my mopidy instance, which seems to fix the issue
