Bug description

A Reshare with (own) group ends up as double share for the sharee.
This problem seems to be only with folders, where you get a reshare which is reshared to a group.
Only occurs to reshares, so not to if you're the owner of a folder and just share it with a group, where you're member of.

Steps to reproduce

Account A shares a folder with Account B.
Account B creates a Team/Group, where he is owner of, and add Account C as member. Let's say Group A.
Account B shares a subfolder from the share of Account A with Group A, with which this reshare also comes into the files overview for Account B.

Expected behavior

For Account B, the reshare should not be shown in the files overview.

Can confirm this is broken and that it works if the shared subfolder is not a reshare.
