In the following situation:
```ruby
class Bar
end
module Baz
end
class Foo
prepend Baz
end
class Foo::Bar
end
```
Running `Inflector.constantize('Foo::Bar')` would blow up with a NameError.
What is happening is that `constatize` was written before the introduction
of prepend, and wrongly assume that `klass.ancestors.first == klass`.
So it uses `klass.ancestors.inject` without arguments, as a result
a prepended module is used in place of the actual class.
