mod_pubsub_serverinfo: Fix check for local domain The module was checking whether a host exists, but this may be misleading if our host is loaded before the host that is being checked. This change makes it check the config. This will provide a false positive in the rare case that the host is defined but not activated/enabled. But we don't have an API currently for "is this host configured and enabled?"

$(function() {
	let jsxc = new JSXC({
		loadConnectionOptions: function(username, password) {
			return Promise.resolve(%s);
		}
	});

	let formElement = $('#jsxc_login_form');
	let usernameElement = $('#jsxc_username');
	let passwordElement = $('#jsxc_password');

	jsxc.watchForm(formElement, usernameElement, passwordElement);
});
