Rails/HasManyOrHasOneDependent does not handle with_options blocks properly

[yskkin]

Expected behavior

There are no offenses when validating a model file with has several has_many/has_one in with_options block.

Actual behavior

If there are two or more has_many/has_one in with_options block, offenses are generated for each association.

Steps to reproduce the problem

Modify a test in spec/rubocop/cop/rails/has_many_or_has_one_dependent_spec.rb as follows.

      it "doesn't register an offense for `with_options dependent: :destroy`" do
        expect_no_offenses(<<-RUBY.strip_indent)
          class Person
            with_options dependent: :destroy do
              has_many :foo
              has_many :bar
            end
          end
        RUBY
      end
