Remove request body from HEAD and DELETE by default

[manuel-watchenterprise]

For specific HTTP methods. For example, DELETE is not officially supported to have request body, however, only GET methods are prevented to have empty request bodies in the output.

@romalytvynenko Actually, I would rather make the default restrict to be ['get', 'head', 'delete'] and so anyone will be able to overwrite this with e.g. ['get'] if they will. But, current implementation is the way around to be completely backward compatible.

Hey @manuel-watchenterprise

Thanks for the PR. For now I decided to keep it as simple as possible while technically changing Scramble behavior – delete and head will not have request bodies. Testing with real API shows that Laravel simply won't "see" params for these methods if sent in request body.
