We are seeing a weird resolution error on Github actions with the
following backtrace:
```
Failure/Error:
visit File.join(
GlobalSetting.relative_url_root || "",
"/session/#{user.encoded_username}/become.json?redirect=false",
)
Socket::ResolutionError:
getaddrinfo: Temporary failure in name resolution
```
Switch to use `127.0.0.1` instead of forcing a name resolution.
