Title: 2.14.0 DeprecationFormatter errors when using ruby-debug

It looks like new DeprecationFormatter doesn't implement start method, so the call is routed to the Kernel method, that is injected by ruby-debug and has a different signature.

```Ruby
module Kernel
def start(options={}, &block)
......
end
end

class BaseFormatter
def start(example_count)
....
end
end
```

Error Message:

```
TypeError: can't convert Fixnum into Hash
