tdf#148522 svx: fix undo of cell border changes text alignment in other cells

The Impress table properties dialog has multiple purposes: normally it
only affects the properties of the currently active cell, but shadow is
applied on the whole shape.

Regression from commit fdeb04f7c59cf8032fe17072ed779e70505cc6ab
(tdf#129961 svx: finish UI for table shadow as direct format,
2020-12-15), we started to apply properties to the current cell, and
then to the whole shape as well, unconditionally. This affects
undo/redo, as there is a separate undo manager while the text edit of a
table cell is active and when the text edit is ended.

Fix the problem by only applying properties on the shape when there we
actually have some properties: this way the text edit is typically not
ended, bringing back the old undo/redo behavior.

Note that we still need to end the text edit if the user explicitly sets
some shadow properties, that part is unchanged with this commit.
