Public bug reported:

[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.
