Memberships table does not re-render when memberships change

[spaenleh]

When a membership changes, the other rows of the table do not re-render.
This is an issue if for example you remove the last before admin, then the hasOnlyOneAdmin will not pass to true and there will be no safety to remove the last admin in the frontend.

Solution

Add the memberships to the useMemo dependencies in ItemMembershipsTable.tsx
