tdf#132956 Chart view: fix missing plot area

Do not reduce the inside area of the chart depending
on the size of the legend. Use the default legend size.

Regression from commit: 739ed2c29f49ea5e83bcd1352b2644c2e2d09f7b
(tdf#115630 tdf#88922 Chart: fix custom legend position and size)

cherry picked from commit cf46500243c51071227e08c5067041e414180ebc
