Allow use of methods for has_many and has_many_ordered

What?
=====

This introduces functionality from
5ef0fd2c0 for has_many and
has_many_ordered macros, allowing methods to be dynamically generated in
those cases.

A simple example:

```ruby
class TodosList < PageEz::Page
  has_many_ordered :items do
    has_one :name, "[data-role='title']"
    has_one :checkbox, "input[type='checkbox']"
  end

  def items(state:)
    "li[data-state='#{state}']"
  end
end
```

With the following markup:

```html
<ul>
  <li data-state="complete">
    <input type="checkbox" name="todos[1]" data-action="mark-incomplete" checked>
    <span data-role="title">Buy milk</span>
  </li>
  <li data-state="incomplete">
    <input type="checkbox" name="todos[2]" data-action="mark-complete">
    <span data-role="title">Buy eggs</span>
  </li>
  <li data-state="incomplete">
    <input type="checkbox" name="todos[3]" data-action="mark-complete">
    <span data-role="title">Buy onions</span>
  </li>
</ul>
```

All of these assertions will work as expected:

```ruby
todos = TodosList.new

expect(todos.items(state: "complete")).to have_count_of(1)
expect(todos.items(state: "incomplete")).to have_count_of(2)

expect(todos).to have_item_at(0, state: "complete")
expect(todos).not_to have_item_at(1, state: "complete")
expect(todos).to have_item_at(0, state: "incomplete")
expect(todos).to have_item_at(1, state: "incomplete")
expect(todos).not_to have_item_at(2, state: "incomplete")

expect(todos.item_at(0, state: "complete")).to have_name(text: "Buy milk")
expect(todos.item_at(0, state: "complete").checkbox).to be_checked
expect(todos.item_at(0, state: "incomplete")).to have_name(text: "Buy eggs")
expect(todos.item_at(1, state: "incomplete")).to have_name(text: "Buy onions")
```
