Fix #1604: NNPFC constraints check
When an NNPFC is activated for a picture, the base NNPFC is added to the list of activated NNPF. The list is later on traversed to check constraints related to the frame-rate upsampling purpose.
The fix consists of adding the NNPFC to the correct list and destroying such list in the picture destroyer.
