[FIX] border: bottom sheet borders removed on DELETE_ROWS

Problem

Before this commit, when we add borders at the bottom of a sheet (at very the last rows), if we delete some rows in a position before the borders, some/all borders disappear (depending on how many rows we deleted). The reason being that the sheet plugin updates the total rows before we loop through them to shift the borders.

Solution

This commit fixes this behaviour by redefining the way we get the border to shift.
