EventListener multiplies itself on login or logout when using platform 'capacitor'

[Physox512]

We have discovered a bug in the plugin, where the EventListener multiplies itself on login or logout when using platform 'capacitor'.
This results in many 400 bad request errors when trying to receive a token from Keycloak:

Also on iOS we had to click on login button seveeral times, before the login really worked...

The solution simply was, to remove the EventListerners after running the Event code in keycloak.js file starting in line 1615:

if (type == 'capacitor') {
    loginIframe.enable = false;

    return {
        login: function(options) {
            var promise = createPromise();
            var loginUrl = kc.createLoginUrl(options);

            const addUrlListener = window.Capacitor.Plugins.App.addListener('appUrlOpen', (data) => {
                window.cordova.plugins.browsertab.close();
                var oauth = parseCallback(data.url);
                processCallback(oauth, promise);
                addUrlListener.remove(); // <--- REMOVE THE EVENT LISTENER HERE
            });

            window.cordova.plugins.browsertab.openUrl(loginUrl);
            return promise.promise;
        },

        logout: function(options) {
            var promise = createPromise();
            var logoutUrl = kc.createLogoutUrl(options);

            const addUrlListener = window.Capacitor.Plugins.App.addListener('appUrlOpen', (data) => {
                window.cordova.plugins.browsertab.close();
                kc.clearToken();
                promise.setSuccess();
                addUrlListener.remove(); // <--- REMOVE THE EVENT LISTENER HERE
            });

            window.cordova.plugins.browsertab.openUrl(logoutUrl);
            return promise.promise;
        },
 ...

@Physox512 For your info, keycloak-capacitor should not have this issue : feel free to give a try :)
