Bug 20891: Escape list's names in JSON

When someone uses \ in the description of a list, the datatable in staff
won't load and keeps processing.

Test plan:
- Create a list named "<script>alert('hola');</script>"
- Create another list named "k\o\h\a"
- Hit /cgi-bin/koha/virtualshelves/shelves.pl

=> Without this patch the lists will not be displayed, JSON is
malformated
=> With this patch everything is ok
