Resolves: tdf#119259 reused in-use SdStyleSheet removed by undo

since...

    n#757432: Styles (rename &) copy to different decks.

    While copying slides to different slide decks,
    styles were not being copied if there is already one
    with the same name. This patch renames and copies those
    to keep the formatting intact.

if a SdStyleSheet is not freshly created, but reused, it ends up in
the rCreatedSheets list, and so when the copy is undone
(via SdMoveStyleSheetsUndoAction), the SdStyleSheet is unconditionally
remove from the StylePool and so its ref count hits 0 and is removed,
even though there are still objects depending on it.

the problem becames more common since...

    Removing old SfxItemSet::getHash usage

improves the SfxItemSet comparison.

Assuming that its correct to leave SdStyleSheetPool::CopySheets
with those reused SdStyleSheets in the list, change things so
that a flag is passed around to indicate if the SdStyleSheet
should be removed or not by undo
