Devices with changed nick/descriptor forget settings

This bug was ported from p-m-s to WP with f8d60fce. Reverting this commit fixes it again.

Bug can be triggered with a config like

-- rg -v -N '^(\s*--.*|\s*)$' /etc/wireplumber/main.lua.d/50-alsa-config.lua
alsa_monitor.properties = {
  ["alsa.reserve"] = true,
  ["alsa.midi.monitoring"] = true,
}
alsa_monitor.rules = {
  {
    matches = {
      {
        { "device.name", "matches", "alsa_card.*" },
      },
    },
    apply_properties = {
      ["api.alsa.use-acp"] = true,
      ["api.acp.auto-profile"] = false,
      ["api.acp.auto-port"] = false,
    },
  },
  {
    matches = {
      {
        { "node.name", "matches", "alsa_input.*" },
      },
      {
        { "node.name", "matches", "alsa_output.*" },
      },
    },
    apply_properties = {
    }
  },
  {
    matches = {
      {
        { "device.name", "matches", "alsa_card.pci-0000_0a_00.1" },
      }
    },
    apply_properties = {
     ["device.nick"]        = "Teufelchen",
     ["device.description"] = "Teufelchen",
     ["device.profile"]     = "output:hdmi-stereo-extra3",
    }
  },
  {

      }
    },
    apply_properties = {
