Incorrect handling of y-protocols/auth messages

[mifopen]

Describe the bug readAuthMessage passes Y.Doc instance to permissionDeniedHandler (or whatever you gave it as the second argument) But permissionDeniedHandler in y-websocket.js thinks it will be a provider https://github.com/yjs/y-websocket/blob/master/src/y-websocket.js#L62

To Reproduce Steps to reproduce the behavior:

1. Send auth message from server
2. See Permission denied to access undefined in logs

Expected behavior See Permission denied to access <URL> or smth in logs

_{Huly®: YJS-528}
