Fix incorrect text when on Airplane Mode

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
Test: atest
