fix(suite-native): enable to confirm receive address outside our app

- We are closing device connection on going to background, so we have to reopen it once needed. We can open the device even on background. But Suite has to be still running, not killed.
- Closing all the devices OnActivityEntersBackground is a good thing because we want to allow other apps (like browser) to work with the Trezor too and it is a good practice to frees up system resources.
