AdapterStatusListener::deviceFound: Resolve sharedDevices persistence of found device via return value

While we keep the device instance temporarily alive within discoveredDevices until next removeDiscoveredDevices() eg at startDiscover(),
we only keep it within persistent sharedDevices list if at least one deviceFound implementation returns true.

This allows user to minimize the sharedDevices footprint when rejecting the device
w/o being required to call device.remove().
