fix: remove persisted emulator's data on deviceLost event

[Fatme]

If the user starts an android emulator from sidekick, {N} CLI persist the emulator in a dictionary. The started emulator is with id emulator-5554 so {N} CLI adds a record with key emulator-5554 in the dictionary.
If the user stops the emulator and starts an another one, the started emulator is again with id emulator-5554. {N} CLI checks that an emulator with id emulator-5554 is persisted and returns the emulator's data. But the returned data is not correct because it belongs to the first started emulator. So we need to remove persisted emulator's data when the user stops the emulator (e.g deviceLost event is emitted).
