DOCX import: fix lost page break when footer ends with a table

Regression from commit 7d3778e0ef9f54f3c8988f1b84d58e7002d6c625
(bnc#816593 DOCX import: ignore page breaks in tables, 2013-09-02), the
page break was ignored because the preceding footer ended with a table
(no empty paragraph at the end of the footer stream).

Fix the problem by saving/loading the table state around header/footers,
that way the page break is not ignored.

Adjust testTdf102466 to test the page number from Word.

(cherry picked from commit a86a2a1c1ceb7203857d4317913c5b1bb9feb4aa)
