let's always disconnect a user connection before dropping the said user. MariaDB is traditionally very tolerant to active connections of the dropped user, which isn't the case for most other databases. Let's avoid unintentionally spreading incompatible behavior and disconnect before drop. Except in cases when the test specifically tests such a behavior.
