IndifferentAccess doesn't respect PropertyTranslation when used in conjuction with IgnoreUndeclared

[whitethunder]

Using Hashie::Extensions::Dash::PropertyTranslation and Hashie::Extensions::IndifferentAccess in conjunction with each other works fine:

class PropertyTranslationWithIndifferentAccess < Hashie::Dash
  include Hashie::Extensions::Dash::PropertyTranslation
  include Hashie::Extensions::IndifferentAccess
  property :baz, from: :bar
end
f = PropertyTranslationWithIndifferentAccess.new(bar: 123)
f.baz
# => 123
f = PropertyTranslationWithIndifferentAccess.new("bar" => 123)
f.baz
# => 123

However, mix Hashie::Extensions::IgnoreUndeclared and it fails:

class AndIgnoreUndeclaredToo < PropertyTranslationWithIndifferentAccess
  include Hashie::Extensions::IgnoreUndeclared
end

f = AndIgnoreUndeclaredToo.new(bar: 123)
f.baz
# => 123
f = AndIgnoreUndeclaredToo.new("bar" => 123)
f.baz
# => nil
