Katie Smith 58cc1604a7 Bump utils and sanitise header values
Updated notifications-utils. This brings in
- the renamed character sanitization classes
- the change to allow unicode in letter addresses (this lets us delete
a test that is no longer relevant)

Also replaced non-ascii characters in headers. This fixes a bug where
non-ascii characters in a CSV filename were causing errors since the
filename is also used in the header.
