screencast: fix pipewire default id_node

Browse source 
The default node_id is SPA_ID_INVALID.

We are casting pipewire uint32_t node_id to int for printing since they are
currently staying in the range of low integer numbers. This makes
spotting an uninitialized node_id (casted to -1) much easier. Should be
corrected if that becomes an issue in the future.
