Crash when capturing 'Expires' cookie attribute

[jcamiel]

With an endpoint returning a cookie without an 'Expires' attribute (or a lowercase 'expires' attributes), if we try to capture this attribute Hurl panics:

google.hurl:

GET https://www.google.com
HTTP 200
[Captures]
value: cookie "SOCS"
expires: cookie "SOCS[Expires]"

Response headers:
