sw floattable: fix inner floating table inside normal outer table from DOCX

The problem was that CppunitTest_sw_ooxmlexport9's testTdf79329 has a
normal outer table and a floating inner table; the inner table was
already not floating (so that's not a new problem), but
SW_FORCE_FLY_SPLIT=1 even failed the text-to-table conversion for the
outer table, so we just had 1 table, not 2 tables.

The problem seems to be that the start/end positions for the outer table
cell get invalidated by the inner table-to-frame conversion, so the
outer table conversion will fail as well.

Fix the problem by limiting the table-to-frame conversion for toplevel
tables: this avoids the failing text-to-table conversion in the
SW_FORCE_FLY_SPLIT=1 case.

At some stage I should revisit this, since the DOC import has working
floating tables for the inner case, for now just make sure that the DOCX
import result has two tables, as before.
