Fix Request.php so HTTP_HOST will take precedence over SERVER_NAME
Fix Request.php so HTTP_HOST will take precedence over SERVER_NAME

In nginx for example the SERVER_NAME is the first value which is configured after server_name

for example:
server_name server1.com server2.com serverN.com

SERVER_NAME in php env will be server1.com
While HTTP_HOST will be the requested URL
