ext_image_capture_source_v1/scene: fix stop for parallel captures

Browse source 
The stop handler disables the output. However, the same source can
be captured multiple times in parallel. In that case, stop might
be called while another capture session is still ongoing.

Only disable the output if the last session is stopped.
