Miscount of roles in spaces

See discussion in common [here](https://common.io/commons/e9f7ecd2-617a-448c-a1b9-e52df9f7d427?item=8ffbc7a7-844e-4b5d-9cca-8547e1539e71)
(Matan:) There's still a bug in the roles count: the system thinks in one place that there is 1 admin in this space, although there are 2 as can seen in another place (see attached screenshots). The same persists in many spaces in the Garden of Life common . More so, since it thinks there's only 1 admin, it doesn't let this admin (myself) downgrade himself to a lower role.
