Fix output and error log in server.py

This patch fixes 2 problems:

1. The '\n' should be in the end of a message,
   not the beginning.

i.e.:
   The original code was:
       sys.stdout.write(_('\nError deleting server'))
   It will make the output look like this:

   [root@tangchen /]# openstack server delete aaa bbb

   Error deleting server
   Error deleting server[root@tangchen /]#

   We change it to:
       sys.stdout.write(_('Error deleting server\n'))
   Then the output will become:

   [root@tangchen /]# openstack server delete aaa bbb
   Error deleting server
   Error deleting server
   [root@tangchen /]#

   which is much better.

2. Record the error in log for those who didn't.
