Fix isc_nm_httpconnect to check for shuttindown condition

Browse source 
The isc_nm_httpconnect() would succeed even if the netmgr would be
already shuttingdown.  This has been fixed and the unit test has been
updated to cope with fact that the handle would be NULL when
isc_nm_httpconnect() returns with an error.
