Sync page orientation of Endnote page

Description:
When changing the default page style to have a different orientation,
end-notes are placed on a page with a custom ‘Endnote’ page style.
This style does not inherit its orientation from the default style.

Repro:
Create a blank document, insert→End Note, Format→Page in the first page,
select the Page tab, and alter the Orientation to Landscape, ‘Ok’.
The End-note page should update its orientation too.

NB. If the Endnote page style is manually set to a different value
in a document template it will remain in the selected orientation.

After this patch, Default style and the Endnote style have their
orientations synced after each run of the Format > Page dialog.

Ideally, this should be solved by resolving tdf#41316 on master:
Page styles should support hierarchical parent-child relationships
(like paragraph or character styles)
