fdo#59953 RTF import: fix unreadable graphic and nested cell contents

There were two issues here:

1) c3b0f13546b30e5db3aecd311c7178e4e0933208 added a mechanism to work
around broken documents, but that didn't deal with nested tables.
Additionally, the check compared the max row width with the width of the
last cell, not the last row.

2) d276d3f3ae112a11c8cb5768650d147cbb94275e cleaned up implicit
horizontal merge detection, but didn't deal with valid documents, where
each row definition is available twice.
