Samples - Ajax - error on page, when Create/Remove button is pressed one by one

[krst]

Test case

• Open Ajax sample in IE6
• Press Create editor
• Press Remove editor, right after (before editor is enabled)
• Press Create editor

Expected result
Editor is loaded after the second press of Enable button.

Actual result Error is thrown

line 141
char 237
error: 'element' is null or not an object
code: 0

Error does not occur in previous versions of samples.
Error does not occur in other browsers.

Probably IE6 is much slower in refreshing new ajax sample.

Regression of [6335].

I was able to trigger a JS error in all versions of the editor (starting from 3.0) using the Ajax sample ("theme is null or not an object", "Permission denied" and other random issues).

We should make sure no error when request to destroy editor before editor finished loading.
