    Fix for RRULE bin parsing for recurrences with modifications
    
    This is an additional fix for Bug #604029
    
    This patch fixes some incorrect parsing that would cause
    exchange_mapi_cal_util_bin_to_rrule() to incorrectly discard RRULE
    information when processing a recurrence containing modified
    instances.
    
    Note that this does *not* include a fix to actually parse the modified
    instances, which after some analysis will be fairly complicated to do and
    thus saved for a later point in time.
    
    The resulting behavior from this patch is that the recurrence will show
    in the calendar, with exception dates for the modified instances, but no
    corresponding events (i.e. the modified instances will be missing).
