DEV: Warm ActiveRecord cache for Sidekiq after Rails initializes. (#14253) 

Sidekiq was failing to boot in dev due to the following error. It seems
like constantizing stuff before the autoloader has kicked in caused
stuff to go weird. Root cause has not been identified but there is no
reason for us to have to warm up the cache during the initialization of
Rails.
