playsink: do not abort if a property is not found.

Browse source 
If a property is not found (for example last-sample when
gst_debug_bin_to_dot_file is used while the pipeline is
slightly broken (thus no last-sample) the unref of the item
gvalue which is not refed fails. Only unref if it was found.
