Remove slash from set-test-mode cmd (for renounce)

(NOTE: We recently applied an identical fix to other tests. This commit
applies the fix to NearbyDevicesRenouncePermissionTest.)

We're currently using the following command to enable/disable Bluetooth
test mode:

    dumpsys activity service X set-test-mode enabled
    dumpsys activity service X set-test-mode disabled

...where X is:

    com.android.bluetooth/.btservice.AdapterService

This is failing.  Change X to:

    com.android.bluetooth.btservice.AdapterService

The reason this broke is that:

1. The slash actually invokes a different syntax, where the part left
   of the slash refers to an APK package name.
2. Bluetooth recently renamed their APK from 'com.android.bluetooth' to
   'com.android.bluetooth.services'.

With no slash, the path simply refers to a Java class package name.
