Avoid wxWidgets alert when removing bottom to top

Fix assert ./src/generic/grid.cpp(5216): assert "idx >= 0 && idx < m_numRows" failed in GetRowPos(): invalid row index happening when selecting >= 3 row starting from the bottom last row. Even if not all row are selected.

This happen because wxGrid::DeleteRows will try to update the selected row between each call.
