sw: split section frames inside table cells, handle nested tables

Commit 3d1bb76ebf5c51141018cfd76eccdb63472de8de (tdf#112109 sw: split
section frames inside table cells, ignore nested tables, 2017-08-31)
explicitly disabled this, but the underlying problem is now fixed with
commit ec262cbc56822d8fffccd6e983848df196cf5c44 (tdf#112160 sw: audit
GetNextLayoutLeaf() calls in SwFrame::GetNextSctLeaf(), 2017-09-04), so
we can have it again.
