Eager loading fix

[aaronwaldon]

Added an element query modification to allow eager loading to work with Focus Point.

I am having issues with Eager Loading still. See these posts.

I am still trying to get to the bottom of it and understand exactly what is causing this to fallover, it seems as though it is getting a value from a previous asset or something?

Digging a little deeper into the database, I noticed two rows for the same asset.
10813 1988 31 0.07 0.17 1989 2018-04-26 20:24:39 2018-04-26 20:24:39 6bfbb940-d66e-418d-b211-6dfa6676acd3

5604 1988 9 0.01 -0.04 1989 2018-03-03 13:52:24 2018-03-03 13:52:24 f68806d6-e332-4881-b5ce-014fe2159571

I am wondering if with this fix, it is in-fact getting/selecting the wrong FocusPoint, where it has been used for a different field. Is there a way to extend this to match the right field ID?

I might be wrong in my assumption, but my PHP isn't strong enough to test or resolve.

Thanks.
