this if branch does not work properly yet, you can also fetch other OnProperty, not just the id

Hello @rbygrave ,
I've been trying to find a solution to the problem in #3644.
I see two ways to approach the problem:
OrmQueryDetailin the select clause instead of fetchPath)SqlTree, when a join would be unnecessary.I've programmed a sketch of the initial idea, which only shows roughly what I envision for the solution. I only provisionally built the extension of the selects in
OrmQueryDetailandOrmQueryPropertiesbecause we would then need such a mechanism; it's probably not 100% correctly implemented.I've disabled one test, which I can look at later. In the subsequent tests, the queries have become simpler.
Can you please take a look at this PR to see if it's moving in the right direction? Or should we pursue the second idea that the simplification only happens later in the
SqlTree?
