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) {
	var self = this;
	var location = window.location.protocol + '//' + window.location.host + OC.getRootPath();
	if(remote.substr(-1) !== '/') {
	remote += '/'
	}
	var url = 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.
