Thumbnails: Capture just before navigating away
Hidden behind new feature CaptureThumbnailOnNavigatingAway.
This is very similar to what NavigationEntryScreenshotManager does.
Hopefully this is a better time for capturing screenshots than when a
page load finishes (see crbug.com/737396 and crbug.com/741856).
