  Log Message:
  -----------
  fix garbage keys in JackPropertyChangeCallback.

Issue
-----
JackPropertyChangeCallback returns a carbage key when removing all keys of
a given uuid, e.g. triggered by 'jack_remove_properties(...)'.

Expected
--------
JackPropertyChangeCallback should return a (NULL) key when removing all
keys of a given uuid.

Culprit
-------
'malloc' is called with key_size==0, which MAY NOT return a (NULL) pointer.

Fix
---
Do not call 'malloc' for key_size==0.
