a user can have access to a file trough different paths, with differing permissions combine all permissions to determine if the user can share this file.

To test:

• create folder /a and /a/b
• share /a with user1 without reshare permissions
• share /a/b with user1 with full permissions
• user1 now has access to b from either /b or /a/b
• as user1 try to reshare /a/b

Currently, the ui shows the option to reshare a/b, but errors when you try to reshare
Sharing /b already works currently.
