Test attribute merging.

Render arrays that use a render element and templates (and hence call template_preprocess()) must ensure the attributes at different occasions are all merged correctly:

• $variables['attributes'] as passed in to _theme()
• the render element's #attributes
• any attributes set in the template's preprocessing function
