Invalid selection after deleting a table.

[Marek Lewandowski]

After removing a table selection is being placed in buggy place, in addition to that editor seems to lose the focus.

1. open any sample with CKEditor (i.e. samples/replacebyclass.html)
2. switch to source and use following source code:

` <h1>foobar</h1>

<p><strong>Apollo 11</strong> was the spaceflight that landed the first humans,</p>

<table border="1" cellpadding="1" cellspacing="1" style="width:500px">

<tbody>

<tr>

<td>&nbsp;</td> <td>&nbsp;</td>

</tr>

</tbody>

</table>

<table border="1" cellpadding="1" cellspacing="1" style="width:500px">

<tbody>

<tr>

<td>&nbsp;</td> <td>&nbsp;</td>

</tr>

</tbody>

</table>

<p><span style="line-height:1.6">Armstrong spent about </span><s style="line-height:1.6">three and a half</s><span style="line-height:1.6"> two and a half&nbsp;</span></p> `

3. switch back to wysiwyg mode
4. remove second table, with one of two options:
   1. right click with your mouse, and use "Delete Table" option
   2. navigate selection using keyboard inside the table, press shift + f10 and use "Delete Table"

Expected result:

1. Table should be removed.
2. Selection should be collapsed, and moved at the begining of next element:

   ^Armstrong spent (...)
   

3. Editor should keep focus
4. No empty line should be visible.

Current result:

1. editor leaves a temporary empty line, where selection is put
2. editor loses focus

additional info:

1. I've experienced it in FF and Chrome @Win7
2. This seems to be not a (recent) regression, because I've been able to repro it in 4.2.3
