Code completion: prefer the first naming environment for range

[auduchinok]

Fixes #18518.

This PR introduces a hack that doesn't let it pick this environment, but it doesn't look correct to me (at least for now). I'm still opening this PR to see if any tests fail.

The main question further is where this environment is created and why doesn't it include the type?
