Fix IMEI information can't display without pSIM inserted

When no SIM, we can't get active subscription info.
So current code will not create TelephonyManager and cause IMEI not
retrieved.
Create TelephonyManager with default if no subscription info.

Test: test with SIM and without SIM to check SIM status UI and atest ImeiInfoDialogControllerTest pass
