Unclear error message "Client Error: Forbidden for url:"

[flossypurse]

When using the store.resolve method, if the promise has already been resolved, an error is returned.

from resonate.storage.resonate_server import RemoteServer
# ...

store = RemoteServer(url="http://localhost:8001")
# ...

store.resolve(
            promise_id="<promise_id>",
            ikey=None,
            strict=False,
            headers=None,
            data=json.dumps(data),
        )

If the promise_id correlates to a promise that is already resolved, we return this error:

{"error":"403 Client Error: Forbidden for url: http://localhost:8001/promises/<promise_id>"}

Receiving an error is probably OK, but if we could make it explicit that the promise has already been resolved that might help debugging.
