Subject: [PATCH] authPrompt: Don't propagate serviceName to setMessage

There isn't always a serviceName when we set a message. Furthermore we
are passing the serviceName only to decide if we want to wiggle or not.
Pass the wiggle parameters instead. If they are missing, we don't want
to wiggle.

This fixes the following error:
JS ERROR: Exception in callback for signal: login-format-changed: Error: Wrong type number; string expected
setMessage@resource:///org/gnome/shell/gdm/authPrompt.js:542:13
_showRealmLoginHint@resource:///org/gnome/shell/gdm/loginDialog.js:931:26
_emit@resource:///org/gnome/gjs/modules/core/_signals.js:114:47
_updateLoginFormat@resource:///org/gnome/shell/gdm/realmd.js:85:18
_reloadRealm@resource:///org/gnome/shell/gdm/realmd.js:57:14
_onRealmLoaded@resource:///org/gnome/shell/gdm/realmd.js:64:14
_makeProxyWrapper/</<@resource:///org/gnome/gjs/modules/core/overrides/Gio.js:245:34
