Indirect share info and owner missing in flat lists

[PVince81]

Steps

1. Login as "admin"
2. Create a folder "test"
3. Share "test" with another user "user1"
4. Create a subfolder "test/sub"
5. Open the share panel for "test/sub" and remember the entries
6. Mark "test/sub" as favorite
7. Go to the "Favorites" list
8. Click the "sub" entry to open the sharing panel
9. Refresh the page
10. Click "sub" entry again

Expected

In the favorites page, the same entries must be visible like for the "All files" page.
This means the share owner, the collaborators and the indirect collaborators.
Same for links.

Actual

On first access, you might see the correct entries because of caching.
After refresh, only the direct collaborators are shown.

Version

0.4.0

Technical

• load sharesTree and incomingShares in state for all parents of the given entry when opening sidebar (and not already cached/populated)
