Update rxrpc-client.ts (#9)

Replace shareReplay with share becasue JavaScript does not support multi-threading because the JavaScript interpreter in the browser is a single thread (AFAIK). Even Google Chrome will not let a single web page's JavaScript run concurrently because this would cause massive concurrency issues in existing web pages.
Also we saw that it working as expected using log prints.
