[FIX] web_editor: fixed the traceback on close modal dialog
[FIX] web_editor: fixed the traceback on close modal dialog

The issue here is, for modal dialogs (eg newsletter popup), when we close
the dialog, the modal is destroyed and so after the delayed execution due to
timeout, the dialog will not be available and it will generate the issue.

removed delayed execution for the traceback, which is relevant to
the modal dialogs.
