ActiveRecord defines automatic scopes for enums, the Poll model defines
an enum for `{open: 1}` this mean Rails wants the scope `Poll.all.open`
to work which in turn means it has to override `open` which is defined
privately.
Rails feature req exists for: https://github.com/rails/rails/issues/34599
which will allow us to define enums without scopes which would resolve this
a lot more cleaner.
