Test plan:
0) Do not apply the patch
1) Have a patron with title/salution filled in
2) Confirm bug, go for example to circ/circulation page and see there is
html in <title> tag (you can see it in your browser page/window title)
3) Apply the patch
4) Go through circulation/patron pages (see modified page above) and
confirm there is no html in <title> tag, but on the page itself the
salutation should be in <span class="patron-title">
