(core) Removing org check in the closeOrg endpoint.

Summary:
Fixing a bug: account couldn't be closed when there was
a team site shared with everyone. Endpoint was checking
if there are any other team sites available, but this is already
tested in "Doom" in a better way, so this check was removed.

Test Plan: New test
