tdf#153196 writerfilter: fix page style for even/odd section break

This is a bit of a special case, where the first section starts with an
evenPage break (\sbkeven), which causes a Left-only page style to be
created.

In completeCopyHeaderFooter(), the HeaderTextFirst and FooterTextFirst
are copied from the source style to the Left-only page style, but then
they also need to be deleted from the source style, because the
Left-only page style is the one that is used for the first page of the
section, and the source style is used for the subsequent pages.

Additionally, when there is *only* a "first" header/footer, and no
previous section has one to inherit, Word will not display a
header/footer at all on subsequent pages; a PageStyle will always have a
header/footer if it has a HeaderTextFirst/FooterTextFirst.

In this case, delete the header/footer from the source style.

Unfortunately exporting this doesn't work ideally, a spurious evenPage
footer will be created, both due to the FooterShare being automatically
reset for no obvious reason in ItemSetToPageDesc(), and
setProperty("FooterIsShared", true) "stashing" the left footer since
commit b802ab694a8a7357d4657f3e11b571144fa7c7bf.

(presumably regression from commit b32881b6723072c8d1a652ea147d12e75766d504)
