After connecting EV3/SPIKE Prime on windows, can't reconnect without first un-pairing #94

Once I have connected to an EV3, and then disconnected, and then restarted Scratch Link (due to the crash in https://github.com/LLK/scratch-link/issues/93), when I attempt to connect again, the EV3 never appears in the scan.

The only reliable way I have found to be able to find and connect to the EV3 is to use the Windows Bluetooth settings to unpair the EV3 (i.e. "remove this device"). After I do that, the EV3 appears immediately in the scan, and I am able to connect.

Scratch Link 1.1.9.0 Chrome 70 Windows 10 Pro 1803 build 17134.345

I'm still seeing this issue, now testing Scratch Link 1.1.11.0, on the same Windows machine as above. The EV3 I have connected to previously, after disconnecting, never shows up again in the scan. I can only make it appear again by using Windows to unpair the device.

Confirmed on Windows 1803 and Scratch Link 1.1.11.0

This is also true for the LEGO SPIKE Prime.
