These 2 tests verify cross-tenant search of groups that belong to a private tenant:

`verify loggedin group search visibility`
`verify private group search visibility`

They are the last 2 requests / assertions of each test.

They verify:

a) A user performing the search from a private tenant cannot get a loggedin (or private), joinable group from an external public tenant
b) A user performing the search from a public tenant cannot get a loggedin (or private), joinable group from an external private tenant

They also verify that if a group is private or loggedin and joinable, and both the source tenant and destination tenant are public, then the groups appear in the results so that the user may request to join them.
