Options hash passed to setter has incorrect value for collection properties

[conradchan]

Problem

options[:fragment] seems to correspond to the wrong property when referenced inside a setter block for a collection property.

Manufactured example:

class DemoRepresenter < Representable::Decorator
  include Representable::Hash

  property :foo
  collection :bars, setter: ->(options) do
    p "Input in setter for bars is value #{options[:input]}"
    p "Fragment in setter for bars is value #{options[:fragment]}"
  end
end

DemoRepresenter.new(OpenStruct.new).from_hash(
  {"foo"=>"fooValue", "bars"=>["barValue1", "barValue2"]}
).to_h

Actual:

The above code prints the following:

"Input in setter for bars is value [\"barValue1\", \"barValue2\"]"
"Fragment in setter for bars is value fooValue"

Expected:

The expected behavior would be for the fragment to correspond to ["barValue1", "barValue2"] since it's in the scope of the bars property.
