General OData error message has extra escaping

Accessing odata4 with an invalid path gives:

{ "error":

{ "code": "TEIID16020", "message": "TEIID16020 Invalid URL, no vdb name found on the path. It should be in the form of \"http:\/\/<host>[:<port>]\/odata4\/vdbname\/modelname\/...\"" }

}

With extra escaping in the url description.
