Bug description:
  [ Impact ]

  A significant number of crashes are being reported across releases in
  the Wireplumber shutdown sequence, particularly when switching between
  sessions (gdm-greeter -> user), but also in other situations.

  [ Test plan ]

  Since this is not an easily reproducible issue, the test plan is
  tricky to define. The code changes can be exercised by
  stopping/starting the Wireplumber service. There are no behaviour
  changes related to the permissions store in particular, rather the
  lifecycle.

  [ Where problems could occur ]

  This could cause / expose further race conditions during Wireplumber
  shutdown.
