framework: last dispatchInterceptor gets asked first

Align implementation with API contract as spelled out in
offapi/com/sun/star/frame/XDispatchProviderInterception.idl -
no idea why this change happenend in 2003:

Date: Fri Apr 4 16:16:05 2003 +0000
INTEGRATION: CWS fwk01 (1.1.72); FILE MERGED
2003/04/01 12:40:09 as 1.1.72.1: #107642# change order of used interception objects

At any rate, with this change extensions actually get a chance to
see dispatch requests first, and process/ignore at will.
