fix: Delete Useless Loading Effetct - Meeds-io/MIPs#120 (#1173)

Prior to this change, a 'displayTopBarLoading' is initiated by application without a corresponding 'hideTopBarLoading' to stop loading effect. This change will delete the display of page global loading effect and rely instead of the internal loading effect added inside the application while loading the news list.
