vmbix-object-sync: get_hosts_by_group returns wrong hosts

[sekyt]

There is array extend method used instead of append in vmbix-object-sync script function get_hosts_by_group. If wrong setup of zabbix groups appears, this function gives wrong results.
Proper function to add another value to the list here is append.
My patch for this is included.
