Have the new account wizard open again

UserModel can't be connected to AccountSettings if the settings dialog
doesn't exist. This is the case now since we delay the creation of that
dialog and free it after use.

Instead it should be properly channeled through the Systray object all
the way up to OwncloudGui which knows how to handle this properly.
