Subject: [PATCH] [contents] Fix parsing of incomplete headers

Response headers may contain fields with no values.

Example:
  "Referrer-Policy: "

In this case the current implementation of explode() results in an
error because there is no content after ": ". Changing the delimiter
to ":" and trimming the value manually fixes that issue.
