[PD] refresh MIDI device list on run

[mario.buoninfante]

What I noticed on Win10 is that if the device is connected when you launch Pd, then you can unplug it and plug it again, without any issues. And one thing more, a new device is detected only if I've never opened the MIDI dialog. I mean:
1. Launch Pd
2. Plug a MIDI device
3. Open MIDI dialog (either from Menu or  within the patch)
4. Pd recognize the device

After I opened MIDI dialog the first time, no new devices will be recognized. That's weird
