https://github.com/drapergem/draper/pull/849 introduced a valid fix to prevent calling object's public method when a decorator overwrites it through a private one. There is one caveat, though. `private_methods` methods has `all` parameter set to `true` by default (https://ruby-doc.org/core-2.7.0/Object.html#method-i-private_methods)`. As a result all private methods are returned, instead of only the ones defined on the object.
This commit fixes the above issue by setting the `all` parameter to `false`.
