Fix/catch device removal error from fido2 lib

[daringer]

Nitrokey3Device.list() and the underlying fido2-library is very flaky during connect/disconnect operations and a regular error thrower, thus after trying with catching only OSError the newly found issue involves a thrown Exception 🙄

  File "lib/python3.10/site-packages/fido2/hid/__init__.py", line 261, in list_devices
    yield cls(d, open_connection(d))
  File "lib/python3.10/site-packages/fido2/hid/__init__.py", line 112, in __init__
    raise Exception("Wrong nonce")
Exception: Wrong nonce

So this PR catches all Exceptions thrown by it and cancels the remove_device operation, which is anyways triggered multiple times so canceling the "bad" ones is fine here.
