Stephan Bergmann f30399c540 Revert "fdo#46808, Convert chart2::Title service to new style" 
This reverts commit d256dbede60533369d1aac64cca34721183f6a8a:

For one, the new css.chart2.XTitle2 looked unfinished, in that it transfered the
direct properties of the old-style css.chart2.Title service into attributes, but
left out all the properties inherited by the old-style service from
css.style.ParagraphProperties, css.drawing.FillProperties,
css.drawing.LineProperties (and that missing FIXME css.layout.LayoutElement,
whatever that is supposed to be).  This needs more thought, to either make
available all propertiers as attributes, or none.

For another, this broke JunitTest_chart2_unoapi (sch.ChXChartDocument,
sch.ChartTitle), for hard-to-debug reasons.

Conflicts:
