beekeeper | Notification about closing wallet is sent multiple times

FYI: @kmochocki @Trela

As the title says, beekeeper looks to be sending a notification about closing wallets multiple times, after actually closing such a wallet.

Path to reproduce looks like:

1. Launch clive
2. Activate with timeout=60s and just wait
3. Clive deactivates after 1min because of beekeeper notification
4. Clive gets another notification about wallets closing after ~14mins since activation
