Avoid throwing a (harmless) exception when we try to write an error response to an http request where the client has disconnected. This comes up as a CRITICAL error in the logs which tends to mislead people into thinking there's an actual problem

…cted (#8465) This PR ports the quick fix from #2796 to further methods which handle media, URL preview and `/key/v2/server` requests. This prevents a harmless `ERROR` that comes up in the logs when we were unable to respond to a client request when the client had already disconnected. In this case we simply bail out if the client has already done so. This is the 'simple fix' as suggested by #5304 (comment). Fixes #6700 Fixes #5304
