publishing with async publisher feature shows the "content is being published".

but, when the publish is done in the preview window, it redirects directly back to parent container(default behaviour wihtout async). the event is correctly processed, is just the redirection that breaks.

test:

• enable asynchronous publisher
• edit any content
• click the preview on the left bar
• publish content from preview page

note: patch from https://jira.ez.no/browse/EZP-22640 must be deployed.
