DOCX table import: fix interaction of 1-cell rows and "inside" vertical borders

The interesting part of the bugdoc was:

- table style wants visible borders
- table direct formatting clears left and right borders
- 1st row of the table has 1 cell (2 cells in fact, but they are
  merged)

Fix the "inside" vertical border handling, so that the first cell gets
these vertical borders as a right border only in case there are multiple
cells.
