Fix a broken test which calls Selection.setPosition(null).

This test was copied from a sibling test:
http://src.chromium.org/viewvc/blink/trunk/LayoutTests/editing/execCommand/indent-images-2.html

This test calls document.getElementsByTagName('div') but there are no div elements.
As a result, test calls Selection.setPosition(null) and it is clearly not intended.
This test uses a span element instead of div element which is targeted in the indent-images-2.html.
Thus this CL rewrite 'div' to 'span'.

This test originally expects that execCommand('indent') should not indent contents inside inline block.
However fixed case, which works as intended, indents the contents.
This CL does only fix broken scripts.

We already started discussion about the execCommand behavior.
If we should change the implementation, we will do it on another patch.

[Regression] Passing undefined to select.add should fallback to the default value

Regression caused by r170259.

Passing an undefined as the second argument of select.add should be handled by falling back to the default value of the optional argument.
