[MapServer-wms]No error is returned when the "time" parameter is empty and the "wms_timedefault" is empty

[nsavard@…]

When a GetMap request is issued with a time parameter NOT set and the
"wms_timedefault" paramater NOT set in the map file WMS server, no error is
returned.  All data is returned instead.  The purpose of this bug is to validate
that we are expecting this kind of behaviour.  If so we should document this
behaviour.

Found on Fedora Core 2

Example of a request:

http://servercgi-bin/mapserv_43?map=/path/to/time_test/htdocs/wms_time.map&
request=GetMap&Version=1.1.1&LAYERS=time&Time=

Associated map file metadata:

  METADATA
    "DESCRIPTION" "time"
    "wms_title" "time"
    "wms_timeitem"  "TIME"
    "wms_timeextent"  "2004-01-01/2004-02-01"   
 END

Checking this ... The specs indocates (section c5.1) that a sercice exception 
with (code="MissingDimensionValue") should be returned.

It now returns an exception (mapwms.c revison 1.119):
