Barnabás Pőcze fa8b0ba018 pipewiresrc: Fix renegotiation
Some downstream elements trigger re-negotiations when the stream is
running, e.g. due to output window resizing for the below pipeline.

gst-launch-1.0 pipewiresrc ! videoconvert ! video/x-raw ! gtk4paintablesink

This fails due to a side effect introduced by commit 77143e54 with
handle_format_change() setting `is_video` to `false` when param was
NULL. Fix this by explicitly tracking media type and not just video
using a boolean.
