Fixing displaying two carriers in split shade header

For dual carriers all carrier information will be displayed inside QSCarrierGroupController and carrier information in StatusIconContainer should be hidden.
The difference in split shade is that for single carrier name of the carrier will be also displayed on the left side in QSCarrierGroupController.

Test: SplitShadeHeaderControllerTest and too much mocking
