tdf#133145 sw ContinuousEndnotes: fix moving endnotes to a previous page

Regression from commit 4814e8caa5f06c4fe438dfd7d7315e4a2410ea18
(tdf#124601 sw: add ContinuousEndnotes layout compat option,
2019-09-30), the problem was that SwFrame::GetPrevFootnoteLeaf() did not
take the new compat flag into account when determining the previous
footnote page for endnotes.

Do the same pattern here as the cases already handled in the above
commit, just try to get the "last but one" and not the "last" page,
since we try to move these endnotes to a previous page.

(cherry picked from commit 35bb0594b2d977312ef06fc5262cc7592bc13d0f)
