Context
Gem itself is done in context that application has at least one enum.
If someone drops all postgres enum related things via migration and dumps the schema.rb, he will have 2 weird empty lines, which he would not have, if he had no gem.
So I've done this little request, so no empty lines would be added in schema.rb if there are no enums.
