cui: fix spell check dialog pointlessly modifying text shape

In Impress, closing the spell check dialog without doing any changes
will replace the entire text of a shape, creating an
sd::UndoObjectSetText and messing up the formatting.

Apparently in commit bbb1428e3666acc7503d86704bbf1e1a4ac04795
a check of the modified flag was removed, but it's not obvious why,
so add it back, which appears to fix the problem.
