wireplumber: fix audio randomly not working at boot time

This issue is caused by a race condition that triggers some links to be
created and then destroyed very fast, but at a certain point where the
managing object (si-standard-link) is not fully configured yet. At that
point, droping the ref count of the si-standard-link doesn't destroy it
and the links remain dangling, causing a loop in the graph that prevents
audio from working properly.

This patch mitigates the issue by forcing si-standard-link to reset to
its initial state, forcing the pipewire links to be destroyed. This does
not, however, prevent the potential leak of the si-standard-link.
A better solution is being worked on for upstreaming.
