Parse set-cookie expires with trailing GMT

[gustafsson]

Set-Cookie with the AlternateRFC1123Format (as in expires=Wed, 23-Nov-2011 01:05:03 GMT) works fine.

But I couldn't see any tests for parsing Set-Cookie with Dates.RFC1123Format, i.e without the dashes as in expires=Wed, 23 Nov 2011 01:05:03 GMT.

Dates.RFC1123Format doesn't include the trailing " G\MT" so we need to append that to the format string.
