security-manager-tests: fix expected error of security_manager_49b_*

The app installation fails because for local installations security-manager
expects that a user's directory in /home exists (/home/tizenglobalapp). In case
of global user there's no such directory. It's not a matter of authentication
but directory existence. Test has been updated to expect
SECURITY_MANAGER_ERROR_SERVER_ERROR rather than
SECURITY_MANAGER_ERROR_AUTHENTICATION_FAILED.
