Daniel Colson 2b524b060d Raise more meaningful error for unregistered trait
Closes #970

In this code we are passing an implicit declaration `user`, rather than
the symbol `:user`:

```rb
factory :post do
  author factory: user
end
```

This will raise a confusing error:
`undefined method 'name' for :comment:Symbol`.

This is coming from the implicit declaration `#==` method,
called on lib/factory_bot/attribute_list.rb#56.
The method wasn't ever designed to compare against
objects of different classes. I added some tests for all the declaration
classes to handle being compared against other kinds of objects.
