New members from an instance with no previous members don't get existing circle shares synced in federated environment.

---

Steps to reproduce

1. setup federation environment with two Nextcloud instances (e.g. nc_1 + nc_2)
2. on nc_1 as bob:

• create test_team and check "Allow federated members"
• create test_folder and share with test_team
• add john from nc_2 (john@nc_2)

3. on nc_2 as john:

• navigate to files > "All files"
• notice how shared folder does not appear

note: if there's already another member from nc_2 on test_team and has access to test_folder, adding a new member does show the resource correctly for them.

Expected behaviour

• john should see test_folder among his files has the resource was shared with a team he belongs to
• entries should be created on oc_circles_mount and oc_circles_mountpoint for given resource on nc_2

Actual behaviour

• john does not see test_folder among his files.
• entries are not created on oc_circles_mount and oc_circles_mountpoint for given resource on nc_2
