Error with database statement in admin/hosts.php

when saving a host in NagiosQL you might get an error message from MySQL / MariaDB stating that the SQL statement host_name`` = 1 WHERE ``id`` = ... (note that host_name and id are encosed in backticks) cannot be executed due to an error

the reason for this can be found in admin/hosts.php in line 498: there is a superfluous backtick after the "SET", after removing it the SQL statement is executed successfully
