Prior to this commit has:link, has:attachment, has:image filter couldn't be applied locally and deferred filtering to web server. This commits make sure client filters all messages it can instead of completely deferring to the server and hence improve speed. A tradeoff is also made to turn off local echo for has: narrows as messages with link sent to has:link narrow were locally echoing to another narrow and not appearing in the active has:link narrow. Fixes: #6186.
