[REVIEW] fix for fdo#46825, crash copying a chart

[Markus Mohrhard]

Hey,

[1] fixes a crash when you copy a chart in the document. The problem
is that you should not create a uno::Sequence with new because the
uno::Sequence copy c'tor is creating a flat copy. This will later
result in a double delete.

I think the patch is quite save and fixes a crash and therefore should
be included into at least 3-5 and if still possible in 3-5-1.

Regards,
Markus
