[PATCH] Fix cache is invalid on empty listing response

[Dmitriy Paliy <dmitriy.paliy@nokia.com>]

Fix cache marked as invalid when no data available in response to get phone
book listing. This fixes obexd crash in 3-way calling scenario. Cache is
created when there is second incoming call. If the call is rejected and
retried again, valid empty cache is sent over obex stream that causes obexd
crash. With this fix, the stream is aborted in such scenario. A new attempt
to create cache is carried out on each new subsequent incoming call.
