    Added a check for attachment['instance']

    The problem, described in the ticket occurs
    while you try to attach a volume to instance,
    while at the same time terminating the instance(
    I've succeeded to reproduce it that way).
    As seen from the stack trace - the error comes
    after an AJAX call for updating the table rows.
    In normal situations with loading the page,
    this error should not appear. Anyway, now there
    is a check to prevent this error.

    Fixes bug 999502
