Share api does not show all reshares

[tobiasKaminsky]

Test scenario:

• user0 creates a folder foo
• user0 shares it without reshare to user1
• user0 shares it with reshare to user2
• user0 share it with reshare to user3

curl --request GET \
  --url 'http://localhost/nc/ocs/v2.php/apps/files_sharing/api/v1/shares?path=%2F&reshares=true&subfiles=true' \
  --header 'ocs-apirequest: true' 

As user0 I do get:

<?xml version="1.0"?>

      <mail_send>0</mail_send>
      <hide_download>0</hide_download>
    </element>
  </data>
</ocs>

So I see all three shares.

As user2:

<?xml version="1.0"?>
<ocs>
  <meta>
    <status>ok</status>
    <statuscode>200</statuscode>
    <message>OK</message>
  </meta>
  <data/>
</ocs>

But I should see user1 & user3 as user2 has "reshare" allowed.
