Omitted auth migration files

[xie-yang]

Hi
here is migration file
return array(
'version' =>
array(
'app' =>
array(
'default' =>
array(
0 => '001_create_companies',
1 => '002_create_users',
),
),
'module' =>
array(
),
'package' =>
array(
'auth' =>
array(
0 => '001_auth_create_usertables',
1 => '002_auth_create_grouptables',
2 => '003_auth_create_roletables',
3 => '004_auth_create_permissiontables',
4 => '005_auth_create_authdefaults',
5 => '006_auth_add_authactions',
6 => '007_auth_add_permissionsfilter',
7 => '008_auth_create_providers',
8 => '009_auth_create_oauth2tables',
9 => '010_auth_fix_jointables',
),
),
),
'folder' => 'migrations/',
'table' => 'migration',
);
but packages folder doesnt include auth subfolder and migration files in it
What's the reason?
