I've only just noticed this now as the game I was playing forced me to change my policy play style mid-game.
Anyway, when you select a policy that gives a free building, the building queue does not clear it from production.
Vanilla Civ does and Civup/GEM still does with Wonders.
To be 100% correct the queue isn't immediately cleared as you would imagine. I don't know if it would clear eventually in a matter of turns, but same turn is preferred.
I'm not sure how often the code checks the queue to remove it, but it surely should be on the same turn as when the policy is selected.
