4. move the export template to dcim | sites

I tried this on v3.0.3 at first and had the same issue. I upgraded to 3.0.4 to see if it was fixed.

I also ran this against the public netbox demo because i wanted to make sure that my devices data wasn't somehow corrupted and causing the issue. I saw the same thing on that site, so I don't think it's my data. It may still be something I'm just doing wrong. This is the first time I've tried to use export templates via the API.
