LT-21778: Fix image textframe styles (#44)

Fixed the problem with the continuation style being written to
paragraphs containing images/captions (instead of the textframe
style being written).
Also, to prevent the problem with the paragraph following the
image/caption from using the textframe style, we now base the
continuation style on the first paragraph instead of the last.
