Fix network category filters when using locales other than en-US

The CL https://crrev.com/c/5938364 changed resource categories to
use an un-localized name as a key, as this was messsing with VE
logging.

This broke the filter UI for non-english locales, as the
NetworkLogView would retrieve the "title" instead of the "name" from
each NetworkRequest to check if a filter applies.

This CL fixes this and adds a regression test.
