[Sharing-NG] creating a drive item with random item id results in 201 response.

[S-Panta]

Describe the bug

Giving any random string ( other than an empty string) as a remote item ID for creating a drive item gives a 201 status code. The response will be empty though.

Steps to reproduce

1. login to ocis as user user.
2. go to shares and make API post request to create a drive item with some string.

   curl -X POST 'https://host.docker.internal:9200/graph/v1beta1/drives/{share-Space-Id}/root/children'  
   -d '{
   "remoteItem": {
       "id":"'123"
   }
   }' -uadmin:admin

3. The status code is 201.

It only checks for valid sharespace id and if remoteitem has empty string or not. What should the expected behavior and status code be?

I think this should return a 400 (Bad Request)
