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.

# Killing a connection in an embedded server does not work like in a normal
|
|
# server, if it is waiting for a new statement. In an embedded server, the
|
|
# connection does not read() from a socket, but returns control to the
|
|
# application. 'mysqltest' does not handle the kill request.
