Core: Double folders when user has a different permission in a group and outside of it

[Trefex]

Steps to reproduce

1. Use ownCloud 9.0.4
2. Have a group (from LDAP) with couple users and a user X
3. Share a folder F with the group and remove write permissions
4. Share the folder F with the user X and give him write permissions
   

   Expected behaviour

User X should see 1 folder F with permissions merged

Actual behaviour

User X sees 1 folder F and 1 folder "F (2)".
