Utils+Everywhere: Add a start offset tolerance for the external player (#2326)

If a current video is practically over or the value in
the history's watch progress is almost the same as the length
of the video, it's safe to deduce that if the external player
button is clicked, the user is most likely just rewatching
the video, making no sense to pass a start offset to it
