Fix: insecure id not set during registration on self hosted (#284)

## Manual Testing
### Verify Bug
- Follow instructions
[here](https://ubuntu.com/landscape/docs/install-landscape-client#heading--install-landscape-client-from-a-PPA)
to install client and use `ppa:landscape/self-hosted-beta`
- Connect client to ppa beta version of self hosted server following
instructions
[here](https://ubuntu.com/landscape/docs/quickstart-deployment)
- After connecting client wait a few minutes and client should go
offline as it is not pinging the server

### Verify fix
- Use this version of client
- Connect client to self hosted server
- Verify ping is working and connection doesn't go offline
