Add schema version to image module for minimal databases

As for #1464554: Upgrade path for image style configuration image module has now hook_update_N functions which is affecting the upgrade path testing (see #1292470-138: Convert user pictures to Image Field) so the schema version in the testing databases should be also changed.

The only change is

->values(array(
  'filename' => 'modules/image/image.module',
  'name' => 'image',
  'type' => 'module',
  'owner' => '',
  'status' => '0',
  'bootstrap' => '0',
  'schema_version' => '8000', <-- From -1 to 8000
  'weight' => '0',

Patch attached.
