Fix widgets layout handle on edit

[VincentMarmiesse]

Hi,
There is an issue when you edit a widget: it does not select the right layout handle.

Example, if you create a core/text_list block on handle cms_index_index:

<?xml version="1.0" encoding="UTF-8" ?>
<layout version="0.1.0">
    <cms_index_index>
        <reference name="content">
            <block type="core/text_list" name="home.area" translate="label">
                <label>Homepage area</label>
            </block>
        </reference>
    </cms_index_index>
</layout>

The area will appear when you create a widget but not when you edit one. That's because the select is not correct in template file.

Test ok.

To reproduce bug :

• create local.xml as suggested
• create a widget and select Display on specific pages > Cms home Page : you will be able to choose the Homepage area added in local.xml
• But as soon as you save the widget (i.e you are now in edition mode), the option disappears from the select.
• On the PR branch, it works as expected.
