Subject: [PATCH] http: CDP ignore invalid content-type message

Saw a site return "Content-Type: charset=UTF-8;charset=UTF-8" on scrape. Not a
valid header and it correctly fails to parse. Except...CDP fails to RI on these
since it tries to parse and bubbles. Safe to swallow this error here and
continue with the response serialization.
