fdo#81893: writerfilter: RTF import: \qc before \page was lost

The paragraph properties need to be applied to the paragraph following
the \page too, which did not happen in this case.

Also the minimized test doc shows that checkNeedPap() must be preceded
by checkFirstRun(), since there is no run preceding the \page.

(regression from 94765a1b)
