GTS: contactsbackup: test failure caused by pre-granting contacts permissions

GTS tests verify pre-granted and default permissions.

It does not like contactsbackup to obtain the following permissions by default:

• android.permission.READ_CONTACTS
• android.permission.WRITE_CONTACTS

To pass GTS these permissions would need to be converted into runtime permissions.

Test

• run gts-dev -m GtsPermissionTestCases --test com.google.android.permission.gts.DefaultPermissionGrantPolicyTest#testDefaultGrantsWithRemoteExceptions
• run gts-dev -m GtsPermissionTestCases --test com.google.android.permission.gts.DefaultPermissionGrantPolicyTest#testPreGrantsWithRemoteExceptions
