Fix for wrong channel

[AdityaMitra5102]

Changes:

• Disable lazy loading for already initialized devices. Fixes the reproducer
• Filter by VID added. We dont need the DeviceManager.add() functions to run if non Nitrokey devices are connected to the PC
• Check for duplicate devices, fixes windows reports Nk3 as three different devices, forcing it into a retry loop

Handles #444

Thanks. Looks like it fixed the problem for me on Linux too. Still needs to be tested for macOS and probably changed to take into account Eric-Canas/USBMonitor#10.
