Remove unneeded decorator

[laritakr]

The code in Hyrax (on the main_before_rails_72 branch) is correct as of samvera/hyrax@28e569f and this override is now incorrect.

This allows for an app to have both lazy migration AND native Valkyrie models without an ActiveFedora counterpart. Without the code changes, hydra_model with lazy migration assumes it needs to add Resource to the model name. And when the Resource model didn't exist, the line returned nil, resulting in the fallback ActiveFedora::Base model to be assigned.
