ARTEMIS-3886 fix CLI operation retry

Commit f8b045bd2d broke the operation
retry as it introduced local variables named "user" and "password" which
overried the class-level variables of the same name. Therefore, when the
user re-enters the username and password on the command-line those
values won't actually be used when attempting to reconnect.
