[Bug]: Factory Resetting does not work if on Pretendo

[ErdbeerbaerLP]

Checked Existing

• I have checked the repository for duplicate issues.

What happened?

When you do a factory reset of a console with an Pretendo Network account, the console cannot complete due to getting 102-2534 (REQUEST_NOT_FOUND).

What did you expect to happen?

The factory reset should finish just fine.

Steps to reproduce?

1. Set up a Wii U (with Pretendo)
2. Connect a PNID
3. Factory Reset

Other relevant information. (OPTIONAL)

Potential Fix, tested with the guys over at Splatfestival.

Make the request PUT http://account.pretendo.cc/v1/api/devices/@current/inactivate return a HTTP 200. Doing this is enough for the factory reset to continue

Pretty sure this is meant to unlink the PNID from the device, or something similar. Not sure what it did on NN.

I can confirm from a capture that Nintendo sent HTTP 200 on this endpoint during a factory reset:

HTTP/1.1 200 OK
Server: Nintendo 3DS (http)
X-Nintendo-Date: 1614906410262
Content-Length: 0
Date: Fri, 05 Mar 2021 01:06:49 GMT
Connection: keep-alive

and thus I have marked the issue as approved. I have not, however, reviewed the Pull Request, and would prefer another developer to do so.
