fix range select

Summary:
Where was a bug, where a range selection using the shift key wasn't working, when the start of the selection was outside the viewport.
The problem was caused by `selectInRange` firing twice, the second time with wrong arguments. In this diff, we are not firing the `onMouseEnterRow` handler, when the shift key is pressed.
