Bug #650241: Fix style for aging table in owner reports that has chan…

…ged (after defining doctype)

Patch by Bert:

Prevent inheriting the parent tablestyle for aging table in owner-report

Bug #650139 & its patch in r20639
have some side-effects:
positive is that borders are shown for empty cell (#642222).

However, the aging table in the owner report now inherits the style from its
parent table, which means that all cells of the aging table are showing as
"centered-label-cell". This means:
*In the regular stylesheet: all text in the cells is bold
*In technicolor stylesheet: all cells have a yellow background

This patch removes the "centered-label-cell" class from the parent table cell
and shows the layout of the aging table to how it was before.
