Subject: [PATCH] Fix list_view-related error in background page

Background page conversations were trying to trigger events on the inbox
list view which had been destroyed, resulting in a background page
console error of "can't read innerHeight of null".

Avoid this by removing listeners when the inbox window is closed.
