Bug when deleting base maps

[harrywipperfuerth]

If several base maps "created" by the user are deleted in the map management "in one process" (= no leaving of the map management), however, only one map is deleted in the view "Activity bar - Basemaps).

The other maps remain available and usable in the view (= show/hide, change transparency ....).

Only when a new map is created in the map management, the project is changed or ODIN is closed, the correct update of the view of the basemaps in the Activity bar takes place.
