elementary/popup : Fixing a bug. Please refer following message from
Rajeev. Thanks Rajeev.
Existing Issue before this change:
   The popup width gets scaled twice when theme_hook gets invoked
because of some reason such as style change, change in elementary
scale factor, change in widget scaling etc.

Change Description:
  Removed setting scaling of internal object wd->base from theme_hook
as it is set to the widget scaling automatically.
