Remove user name from public sharing page

[nickvergessen]

Need to check the fallback from:

server/apps/files_sharing/js/public.js

Lines 391 to 419 in 5e4eda1

	_legacyCreateFederatedShare: function(remote,token,owner,ownerDisplayName,name,isProtected){
	varself=this;
	varlocation=window.location.protocol+'//'+window.location.host+OC.getRootPath();
	if(remote.substr(-1)!=='/'){
	remote+='/'
	}
	varurl=remote+'index.php/apps/files#'+'remote='+encodeURIComponent(location)// our location is the remote for the other server
	+"&token="+encodeURIComponent(token)+"&owner="+encodeURIComponent(owner)+"&ownerDisplayName="+encodeURIComponent(ownerDisplayName)+"&name="+encodeURIComponent(name)+"&protected="+isProtected;
	if(remote.indexOf('://')>0){
	OC.redirect(url);
	}else{
	// if no protocol is specified, we automatically detect it by testing https and http
	// this check needs to happen on the server due to the Content Security Policy directive
	$.get(OC.generateUrl('apps/files_sharing/testremote'),{remote: remote}).then(function(protocol){
	if(protocol!=='http'&&protocol!=='https'){
	self._toggleLoading();
	OC.dialogs.alert(t('files_sharing','No compatible server found at {remote}',{remote: remote}),
	t('files_sharing','Invalid server URL'));
	}else{
	OC.redirect(protocol+'://'+url);
	}
	});
	}
	},

It seems like at least the userId is required to be leaked non the less, if we want to continue having this fallback available.
