Most of this was fixed by adding the `attribute-defined-statically-cop`
branch of `thoughtbot/rubocop-rspec` to the Gemfile and running:
```sh
rubocop \
--require rubocop-rspec \
--only FactoryBot/AttributeDefinedStatically \
--auto-correct
```
I had to update the cucumber tests manually, and I realized our changes
don't handle `ignore` blocks or blocks with arity 1 that use the yielded
DefinitionProxy. I will update
https://github.com/rubocop-hq/rubocop-rspec/pull/666to handle these
cases.
Ruby 1.9 doesn't automatically include . in the load path; if we do a
require to a relative path (eg a file within spec or test), 1.9 will raise a
LoadError because spec or test isn't normally in the load path.
