Space disable/delete operation returns 404 instead of 403/401 in case of no permissions

## Describe the bug

If any user with no permissions disables a space, a `404` is returned. `404` means `Not Found` but the space is there, in front of his/here eyes.

`403 Forbidden` or `401 Unauthorized` fits better to such situation and helps clients to show a proper error message.

## Steps to reproduce

1. A user in Android client with `manager` permission over the space lists the available operations for his/her role over the space
2. Before submitting any operation, that user is downgraded to `viewer` in the space
3. User clicks on `Disable space`

## Expected behavior

`403 Forbidden` or `401 Unauthorized` returned by the `DELETE` request

## Actual behavior

`404 Not Found` returned. Following the steps above, the space is not disabled because lack of permissions and is still visible and displayed, so that, `Not Found` is not correct.

## Setup

Perform the following `curl`

```
curl -H 'Original-Request-ID: 033BCBF5-9812-46C0-81F3-722998AD7FB9' -H 'Connection: keep-alive' -H 'Accept: */*' -H 'Accept-Language: en' -H 'Authorization: Bearer xxx' -H 'X-Request-ID: 033BCBF5-9812-46C0-81F3-722998AD7FB9' -X DELETE 'https://xx.xx.xx.xx:9200/graph/v1.0/drives/'
```
