[DolphinView] Fix "Folder is empty" label showing prematurely
Don't show the label while still loading. Since there is no property in `KDirLister` a dedicated `m_loading` is added for this purpose. Also, I removed the explicit update on `urlChanged` as the view probably won't change until the lister starts loading. BUG: 430085
