Observing Wishlist is truncated upon adding object from the popup menu, before the wishlist is loaded (by firing the Obs. Planner)

To reproduce:

• Fire up KStars
• Right click on any object > Add to Observing Wishlist
• Fire up the Observation Planner (Ctrl + L)
• Your old wishlist entries have vanished because the addition before the loading of the wishlist truncated it

Should be an easy fix: Simply load the wishlist when the first request to add to the wishlist appears. Even better: Load the wishlist in a background thread after full startup of KStars
