Bug description:
  [Impact]
  LightDM doesn't support the XDG standard "DesktopNames" field in session .desktop files. Instead we only support X-LightDM-DesktopName which was used before the standard was set. Newer sessions might expect DesktopNames to work.

  [Test Case]
  1. Install a session which has DesktopNames set in /usr/share/xsessions/name.desktop. i.e. DesktopNames=GNOME;Unity;
  2. Start this session
  Expected result:
  XDG_CURRENT_DESKTOP is set to GNOME:Unity
  Observed result:
  XDG_CURRENT_DESKTOP is not set

  [Regression Potential]
  Low. This feature is only activated if the field is set.
