Only generate missing sim text if there are no CarrierName present AND
no sims READY. This was an issue when airplane mode with WFC.
Also, replace using mCarrierGroups[0] for its text when the sims are
missing. Instead use a different view that is made visible when all the
QSCarrierGroups should be invisible.
Test: manual, using APM
