Triple click correction failed whenever the triple-click-selected block
was followed by an empty block. The reason is that `getDeepestPosition`
prevents the selection from being placed within a line break (`<br>`)
and therefore returns the block itself (`<p>[]<br></p>` will be
expressed as `(p, 0)`), so the heuristic to determine if triple click
correction in needed in `getDeepRange` would fail as it assumed the
`end` node was a leaf where it wasn't. This fixes the issue by applying
the heurstic to the first leaf of the `end` node instead, and making the
correction for there as well.
