Subject: sw: fix ViewCursor.PageStyleName for multi-page paragraphs

In case the text frames of a text node span over multiple pages and the
first page has a page style which has a follow page style, the page
style under the cursor depends on not only the text node index, but also
on the context index.

Without this, the page style under the cursor will expose the first
page's style name via the API, even if it's already on a follow page.
