fix: SOAP vcSessionCookie value must be from vim25.Client

Commit 1918984 refactored how we set vcSessionCookie for pbm and vslm endpoints.
We need to use the value of vim25.Client's vmware_soap_session for vSessionCookie.
Since the first response from pbm/vslm includes a 'Set-Cookie: vmware_soap_session=...',
the value of which is _not_ valid for vcSessionCookie.
