Casting drops the strict_loading state of an ActiveRecord object

I was recently faced with N+1 queries which surprised me as I had strict_loading enabled in every controller.
Digging into the issue I noticed that active_type drops the strict_loading state after casting an object:

user = User.strict_loading.find(3)
user.strict_loading? # true

casted_user = ActiveType.cast(user, User::Form)
casted_user.strict_loading? # false

A quick workaround would be to re-enable it after casting:

casted_user = ActiveType.cast(user, User::Form).tap(&:strict_loading!) if user.strict_loading?
casted_user.strict_loading? # true

I think it would make sense to fix this in the gem itself, WDYT?

Yes, that's definitely something ActiveType should fix.

Okay. 👍

I just had another look at all boolean methods of an example AR-instance. We should probably check all of those while fixing the issue above:

 :strict_loading?,
 :strict_loading_n_plus_one_only?,
 :readonly?,
 :frozen?,
