Bug 23093: (bug 22318 follow-up) Use placeholders in query moving OpacNavRight

Placeholders must be used (!) in all SQL queries.

Test plan:
1/ % git checkout 0c95e22afe13349b60d134217fce6718bfa9727f # commit before bug 22318
2/ Edit the pref OpacNavRight with something with "
  just a " and more '
3/ git checkout master
4/ restart_all
5/ run updatedatabase.pl
=> Boom and the content of the pref has been lost
6/ Repeat 1 to 3
7/ Apply this patch
8/ run updatedatabase.pl
=> The pref has been correctly moved to opac_news
