halfway solution for minitest / shoulda-matchers

The `Warning: you should require 'minitest/autorun' instead.` error
doesn’t actually stop the tests from running, so I think we can live
with it for now. thoughtbot/shoulda-matchers#434 resolves the error,
but the currently unresolved thoughtbot/shoulda-matchers#473 prevents
us from just using master.
ignore `select` clause inside `collection_size`

Rails 4.1 doesn’t handle multiple `select` arguments well when calling
`count`. This:

```ruby
User.select(:id, :name).count
```

Results in:

```sql
select count(id, name) from users;
```

add pry to the Gemfile because it's awesome :heart:
