tdf#150616 sw: fix bad 0 height of SwTextFrame in table cell

The bugdoc has a text frame 42 immediately following a section which
contains a nested table, both inside a table cell 29.

The problem is that with soffice --convert-to pdf, the height of frame
42 ends up as 0, after a single layout action; this does not happen when
loading it from UI.

When the frame 42 is formatted, it calculates the needed height, and
grows, but in SwTextFrame::AdjustFrame() it doesn't fit into its upper
cell frame with a negative nRstHeight at this point, and the text frame
is reduced to height 0.

The odd code in SwContentFrame::MakeAll() exists unchanged since CVS
initial import and is poorly motivated. It is highly suspicious that it
simply grows the upper frame, without invalidating the size of the
current one (which was already shrunk), and/or clearing the
m_bUndersized flag.

If this code is removed, on formatting the next frame 43, it goes up and
formats the cell frame, which grows and at the same time importantly
invalidates the text frame 42, so it will be formatted again and full
height.

At the point when the frame 42 was formatted, its upper cell frame was
size-invalid, so it looks like that will be formatted eventually in any
case and then invalidate 42.
