Update ManageExternalStorageDetailsTest setUidMode

We previously changed ManageExternalStorageDetails to use
AppOpsManager#setUidMode instead of AppOpsManager#setMode, but forgot to
update the relevant unittest. This CL changes that unittest.

Test: make RunSettingsRoboTests ROBOTEST_FILTER=ManageExternalStorageDetailsTest
