[BUGFIX] Workspace relations in ElementInformationController

When relations are added in a workspace, the 'info' modal
of the parent record does not reflect those. The patch changes
the reference resolving to work with the overlay record uid if
given. This fixes reference record display for inline records
including file references.
There are further issues with the rendered record, those
however are resolved by other core methods and can be
fixed with other patches.

Resolves: #45148
Releases: master, 10.4
