tdf#108921 : Enforce a minimum legend size for pivot charts...

...proportional to the chart size. This lets a default pivot
chart maintain its current size even when there are no data points
which may result from a pivot field filter operation.

Tried to add a test, but could not with a reasonable amount of
effort.

Some observations I made when tried to create a unit test:

1. If a new chart is created using uno api fresh from a pivot table,
   no legend is created irrespective of whether there is data or not.
2. Pivot charts with zero data points work fine with this patch, but
   on round trip the chart needs to be explicitly refreshed by
   clicking one of the pivot table's field selectors to make the chart
   show axis/labels etc.
