Don't show "device" on SIM import after account added

If "Device" was set as the default it would stick on the SIM import screen
even after a Google account was later added.

Test
manual:
* have device with no accounts
* set default account to "Device"
* verify that "Device" is destination on SIM import screen
* add Google account
* verify that Google is destination account on SIM import screen
* verify that "Device" is no longer shown as option on SIM import screen
