remove page count check in a test (irrelevant and fragile)

If I load this document in LO, either my build or distro build, it has only
one page, so the test fails for me only because of the 2-page check.
The commit causing this, b904d639a8, has been in for quite a while,
so it's apparently something special about my setup, but a) the test
doesn't actually require 2 pages for anything, b) the commit mentions that
the test is fragile, c) if I manually inspect the .rtf, there's an extra page
that I do not see even in Word2013, so the document is possibly a bit broken.
One way or another, the page check seems pointless.
