Don't reset the page selection if the results have changed while the user

Browse Source 
was browsing exiting results

This is most noticeable when viewing results in xephyr, and then opening
a document in your regular session. But it could also be noticeable if
downloading a new file completes while the user is in the overlay.

This patch also moves the call to _displayMatchedItems() to _redisplay
instead of making it in both _setDefaultList() and _doSearchFilter().
