Testing

Describe the best way to test or validate your PR.

This is actually like a philosophical question: how can I test something that actually don't exist?

One of the searches I made for "testing" that these strings are unused:

$ egrep -ri "(document_id|province|address|post_code)" .|grep -v config/locales 
> ./spec/services/decidim/initiatives/data_encryptor_spec.rb:          postal_code: ::Faker::Address.zip_code }
> ./spec/cells/decidim/initiatives_votes/vote_cell_spec.rb:      postal_code: ::Faker::Address.zip_code
> ./spec/commands/decidim/initiatives/vote_initiative_spec.rb:          postal_code: ::Faker::Address.zip_code

Note that postal_code is unrelated to this block.
