Fix/support multi relation property

[rimonhanna]

Description

A database with sub-items enabled
Add multiple sub-items to a single "parent" page
Open parent page:
Previously: It showed only the first child/sub-item as the returned recordMap only included the full information of the first, and only the Ids of the others
Now: It attempts to fetch all children/sub-items blocks and shows them as expected

hmmmm the minimal example is intentionally minimal and does not support relations / collections.

@rimonhanna does your use case work with the full example? that's meant to handle this case.

[rimonhanna]

@transitive-bullshit done

[rimonhanna]

best way to test it, is to enable sub item in this collection and create a few sub items to one of the database items
