[PATCH obexd] Fix pulling single vCard for parameters header missing

According to PBAP specification (ANNEX A), all application-parameters
are optional in case of pulling single vCard entry, so header for
application-parameters can be omitted, and it would be valid as well.
Previously pulling single vCard was always failing with "Bad Request"
status in such a circumstance.
This patch fixes that issue and pulling single vCard is done successfully
with "OK" status. Output vCard would contain all fields under 2.1 format
(as for default settings).
