    Fix instance dir check when spawning

    When spawning instances, we're checking if the instance dir
    already exists, in which case we're logging a message, stating
    that existing instance files will be reused.

    Well, at least that's what we thought we were doing. Actually,
    we're always logging this message as the check is wrong.

    This change fixes this issue.
