Title: Don't include base in error messages

In Rails there is a distinction between field validation error and base validation error.

```ruby
foo.errors[:title] << "is too short"
foo.errors[:base] << "A generic model error"

foo.errors.full_messages
# => ["Title is too short", "A generic model error"]
```

Let's reflect this and stop hacking this behaviour in each project.
