title: WidgetKit getCurrentConfigurations returns wrong list of widget-configurations
body: <p>I've added Widget Extension with Configuration Intent.
  For the logging purposes, I've tried to log number of widgets user of the app has</p>
  <pre><code> WidgetCenter.shared.getCurrentConfigurations { results in
       guard let widgets = try? results.get() else { return }
       ..&lt;log widgets.count&gt;...
   }
  </code></pre>
  <p>To my surprise, instead of the active [WidgetInfo]'s I've got a whole list of all the configuration intents ever been used in all the widgets instead of the actual ones.</p>
  <p>I.e. I have 2 widgets on the screen, while <code>WidgetCenter</code> claims I have 9 current configurations. Any better ideas how to count widgets?</p>
