API: Minor fix for team creation endpoint when using API key (#18252)

* Fix CreateTeam api endpoint

No team member should be created for requests
authenticated by API tokens.

* Update middleware test

Assert that `isAnonymous` is set for `SignedInUser`
authenticated via API key.

* Add test for team creation

Assert that no team member is created if the signed in user
is anomymous.

* Revert "Fix CreateTeam api endpoint"

This reverts commit 9fcc4e67f589008d7c44097f5cf08438c09c3c05.

* Revert "Update middleware test"

This reverts commit 75f767e58d212e21a351efea14bed79bbf881d2e.

* Fix CreateTeam api endpoint

No team member should be created for requests
authenticated by API tokens.

* Update team test

* Change error to warning and update tests
