Fix reauth without password

[fisx]

galley end-points for deleting team members and deleting teams, resp., ask for a password even if the user calling the end-point doesn't have one. we change the behavior to be in sync with the end-points for adding and deleting devices.

For password-less users, I'd just change the test so that no login is performed, i.e., one could simply skip:

     -- Permanent client with attached cookie
     login brig (defEmailLogin email) PersistentCookie
         !!! const 200 === statusCode
    numCookies <- countCookies brig uid defCookieLabel
    liftIO $ Just 1 @=? numCookies
