Test rendering for conversion metric filter

Description

Rendering test for a conversion metric filter.
I intended to add a check query test, too, but the SQL result turned out so complicated that it didn't seem particularly useful.

Yeah, for conversion metrics I think we need to do output checks - it's often easier, with a simple example, to do the math than it is to figure out how to write the SQL.

Nice spot. Conversion metrics are so incredibly complicated.....
