    Do not hide exception in update_instance_cache_with_nw_info

    From time to time an exception is raised in this method causing
    the nw_info cache not to be saved. If this occurs we should raise
    as this error will cause later errors to occur. For example, one
    won't be able to associate a floatingip with the instance as there
    is no nw_info found in this table. In addition, the fixed_ips on
    the instance won't be returned via the api.

    This patch also stubs out update_instance_cache_with_nw_info in a
    few tests where an exception was being raised previously but went
    unnoticed as it was not reraised but now is.
