Error when deleting an institution whose auth method is in use

[Richard Mansfield]

When you delete an institution, and one of the institution's authinstances is still in use by some users, you get an sql error and a nonrecoverable error screen. (This can only happen when the users still using the authinstance are not institution members, because there is already a check to stop deletion of institutions with members).

    Check for authinstances in use when deleting institutions (bug #917873)

    When you delete an institution, and one of the institution's
    authinstances is still in use by some users, you get an sql error and
    a nonrecoverable error screen. (This can only happen when the users
    still using the authinstance are not institution members, because
    there is already a check to stop deletion of institutions with
    members).

    This patch allows the institution to be deleted anyway, reassigning
    the offending users to a 'default' authinstance. If we can't find a
    sensible default authinstance, it will at least display a more helpful
    error message.

    Also, when attempting to delete an institution with members, set an
    error on the form rather than throwing a ConfigException.
