  Broken dbus GetAll message to wpa supplicant interface properties

Status in wpa package in Ubuntu:
  Fix Released
Status in wpa source package in Bionic:
  Fix Released

Bug description:
  * Impact
  One of the distro patch is incorrect and create issues when trying to query 
dbus properties

  * Test Case

  $ sudo dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1

  shouldn't error out

  (the /1 reflect the interface number and could be a different value,
  check with d-feet if needed)

  * Regression potential

  The fixes is in the dbus interface, check that communication with
  desktop clients (indicator, applet, settings) still works correctly,
  returning expected informations on the signal, etc


  dbus-send is able to read the properties of interface using GetAll. Those 
information include interface name, status, encryption method, etc.
  The regression was introduced when someone try to have the Station attribute
