Subject: [PATCH 12/17] Fix: scheduler: consider explicit colocations with
 group members

Previously, a group's colocations would include only colocations explicitly
with the group itself, and with its first member (for "group with" colocations)
or last member (for "with group" colocations). Explicit colocations with a
different group member could cause incorrect node assignment.

Fixes T679
