crashtesting: downgrade assert on bookmark missing from input docx to a warning

The docx bugdoc is "generated by ComMA version 3.3.0" and has a pair of
bookmarkEnd/bookmarkStart in a non-conformant order, like so...

<w:bookmarkEnd w:id="23"/>
...
<w:bookmarkStart w:id="23" w:name="_Toc483311613"/>

both bookmarkStart and bookmarkEnd are mapped to the same
DomainMapper_Impl::StartOrEndBookmark
(without a distinction made between begin/end) which assumes the first
time it's called for an id that it's a bookmark start, and the second
time for an id that it's a bookmark end and that there will have been a
w:name seen between the 1st and 2nd calls to be used as the name for the
bookmark to use at the 2nd call.

That there is no bookmark name is a problem in the input docx rather
than the import logic so turn this assert into a warning
