Code review comment for lp:~ted/unity8-desktop-session/snap-session

I built the package, added a local apt repository with the 3 debs generated, then tried to install unity8-session-snap and apt wants to remove the following packages:

The following packages will be REMOVED:
  dbus-user-session ubuntu-desktop ubuntu-session unity8-desktop-session

I don't thikn we want the ubuntu-desktop task and ubuntu-session packages removed. This is due to the Conflicts of dbus-user-session. I don't entirely understand why that is a Conflicts...
