allowlakeprod are outputing standard variables instead of the "lake" specific versions...

When allowlakeprod is on, the lake specific version of variables should be output, and yet it's outputting the non-lake versions which already are output.

This is in clm4_5_16_r241. I need someone to look at this and check if I'm right about this or not. I noticed this looking at the code for other issues.

If this is a legit problem it goes back to the beginning of this work. The changes below also do work.

It also appears that we don't have any tests for allowlakeprod.

Add Zack to the CC list.

Zack is no longer working in the field so is not likely to comment. We do not and have not used the lake production code so if this is a bug, it hasn't affected anything. We have no current plans to use it, either, though if the fix is easy, we should go ahead and do it.

We don't test this configuration. So closing as a WONTFIX.
