Browser: fix force close when remove a history

The delete item id in bookmarks page, history page
and snapshot page is the same, when tap delete item
in history page, the event was handled by snapshot
page, then an exception happened.

If current context menu doesn't belong to current
page, let other fragment deal with it.
