Remove setAccurateVisibleContentsPosition codes because it is not needed anymore.

[Title] Remove setAccurateVisibleContentsPosition codes because it is not needed anymore.
[Issue#] N/A
[Problem] The setAccurateVisibleContentsPosition codes are not needed anymore.
[Cause] We call the initializeVisibleContentRect() and it set the accurateVisibleContentsPosition by
        calling setVisibleContentRect(), so we don't have to set accurateVisibleContentsPosition separately anymore.
        I know the setAccurateVisibleContentsPosition() is added for fixing N_SE-15113,
        and I've checked that defect does not occur without setAccurateVisibleContentsPosition() codes now.
[Solution] Remove setAccurateVisibleContentsPosition codes.
