tdf#95295: don't add duplicate conditional formats

This tries to make sure that on copy, any conditional formatting
that has same entries (conditions and formats) as another condition
in the table, is not appended to the conditions list, but updates
existing condition's range. This should prevent multiplication of
entries with duplicating conditions and formats, and fragmenting
ranges.

Existing unit tests had to be adjusted, because they had ensured
exactly that behaviour that is changed in this commit: that new
items are added to the list, and e.g. multiple elements are created
when a single cell is copied to a range.
