fdo#78883: Writer getting Hang while opening document

Description:
Writer getting Hang while opening document because of loop in layout.

Root cause: For Documents containing table with direct formatting for
Para line spacing along with style w:type="table" in style.xml LO was
erasing PROP_PARA_LINE_SPACING Prop from pAllCellProps in
DomainMapperTableHandler::endTableGetCellProperties().  But for
Documents without direct formatting for Para line spacing this deletion
was causing problem, as after deletion there is no formatting available
to apply.

To fix this checking whether there is a Direct formatting available for
table, if Yes then proceed with this deletion logic.
