osis2mod: bug in handling preverse material

When a chapter is of the form <div type="chapter"> rather than <chapter>, the first </div> is seen as its close when it comes to pre-verse material. The consequence of this is that pre-verse material is appended to the prior verse, as if it is the last verse in the chapter.

Here is an example:
<div type="chapter" osisID="Matt.6">
<div type="section">
<title>Title for section starting at Matt 6.10</title>
<verse osisID="Matt.6.10">Content of Matt.6.10</verse>
</div>
<div type="section">
<title>Title for section starting at Matt 6.11</title>
<verse osisID="Matt.6.11">Content of Matt.6.11</verse>
</div>
</div>
