Bug 25804: Remove HTML from title tag of bibliographic detail page

This patch removes <span> tags from the bibliographic detail page's
<title> tag.

To test, apply the patch and view the bibliographic detail page for
any title in the staff interface. In the page title shown in the browser
tab you should see no <span> tags.
