Upnp Port does not close upon exit of nicotine+

[Sakooooo]

Nicotine+ version:
Operating System/Distribution:
Windows 10 21H2

Describe the bug

When exiting Nicotine+ and then going into my router's upnp page it says that nicotine+ is still opening the port

Expected behavior

Upnp should say the port is closed and should open again on next launch

Steps to reproduce the bug

1. Open Nicotine+ with UPNP port forwarding
2. Open router UPNP homepage
3. Close Nicotine+
4. Port should say it is still open

Small Workaround until it is fixed

1. Turn off Upnp
2. Turn it on again

This also happens with the original SoulSeek Client

The port mapping expires after 24 hours, but I suppose we could also remove it when closing Nicotine+.

I think it would just be better to just add it as an option in that case
