Error thrown when we press delete after first list item in a Numbered/Bulleted list inside a table

[Satya Minnekanti]

To reproduce the defect:

1. Open any sample and insert a table.

2. Keep cursor inside a table cell & click on Numbered/Bulleted list icon in the toolbar to start a list

3. New list created and cursor stays after first list item in Numbered/Bulleted list

4. Press Delete

Expected Result: Nothing should happen

Actual Result: In IE A javascript error thrown & error is Unable to get the value of the property is: object is null or undefined.

In Firefox list is deleted

I actually got error in every Browser. Chrome and IE don't remove bullet while Firefox does but every browser throws error:

Message: TypeError: nextBlock is null
Code: if ( nextBlock.is( 'li' ) ) {
URI: /ckeditor4/plugins/list/plugin.js Line: 721

Problem can be reproduced from CKEditor 3.6.4 rev. [7540]

Add the table with the list inside:

<table border="1" cellpadding="1" cellspacing="1" style="width:500px">
	<tbody>
		<tr>
			<td>
			<ol>
				<li>One</li>
				<li>Two</li>
			</ol>
			</td>
			<td>Test</td>
		</tr>
	</tbody>
</table>

Move cursor to the end of the second item of the list and press Delete.
