# The class FoundOrganisationProposal was renamed to FoundAssociationProposal in
# 3967f8a8dbdea4f8a6556e72f710dfc0639941c4. However, existing records in the `proposals`
# table still have the `type` column filled in with 'FoundOrganisationProposal'. To avoid
# `ActiveRecord::SubclassNotFound` errors, we need to rename them to match the new class
# name.
