/db/post_migrate/20160824121037_change_personal_access_tokens_default_back_to_empty_array.rb

 1# The default needs to be `[]`, but all existing access tokens need to have `scopes` set to `['api']`.
 2# It's easier to achieve this by adding the column with the `['api']` default (regular migration), and
 3# then changing the default to `[]` (in this post-migration).
