- The `scopes_form` partial can be used in the `admin/applications` view
as well
- Don't allow partials to access instance variables directly. Instead, pass
in the instance variables as local variables, and use `local_assigns.fetch`
to assert that the variables are passed in as expected.
- Change a few instances of `render :partial` to `render`
- Remove an instance of `required: false` in a view, since this is the default
- Inline many instances of a local variable (`ip = 'ip'`) in `auth_spec`
- The list of scopes that's displayed while creating a personal access
token is identical to the list that's displayed while creating an OAuth
application. Extract these into a partial.
- The list of scopes that's displayed while in the show page for an OAuth token
in the profile settings and admin settings are identical. Extract these into
a partial.
- Mainly whitespace changes.
- Require the migration adding the `scope` column to the
`personal_access_tokens` table to have downtime, since API calls will
fail if the new code is in place, but the migration hasn't run.
- Minor refactoring - load `@scopes` in a `before_action`, since we're
doing it in three different places.
