Bug 17736: [QA Follow-up] Crashes in basket.pl and parcel.pl

Crash in basket.pl:
Can't call method "holds" on an undefined value at /usr/share/koha/masterclone/acqui/basket.pl line 466.
Comes from a biblionumber == NULL in aqorders where I cancelled the order and deleted the biblio.

Crash in parcel.pl:
Can't call method "holds" on an undefined value at /usr/share/koha/masterclone/acqui/parcel.pl line 246.
Similar fix.

Trivial fixes indeed.
