Login\ACL revalidate flow fixes

- DB function had wrong column name
- Queries in ACL\Login had wrong column name
- Renamed from login_user_id_last_login to login_user_id_last_revalidate
  to make it more clear what this column is
- add edit_user admin page output for this column
- add phpUnit test case for revalidate is needed and login with next
  loginUserId is ok again
