Evaluating the return value of 'json_load' didn't work in the
intended way resulting in PIN status no longer being read on modems
where --get-pin-status doesn't fail.
Fix this by trying --get-pin-status first and checking if pin1_status
field exists in JSON, and if it doesn't try again with
--uim-get-sim-state.
Fixes: #9501
