When moving an instance to the same cluster target group it already belongs to, another node needs to be picked in case it currently hosts the instance and got selected due to least amount of instances. Signed-off-by: Julian Pelizäus <julian.pelizaeus@canonical.com>

First observed in #12143.
When moving instances within the same cluster group, the node which is currently hosting the instance should not be selected by the scheduler due to having the least amount of instances.
GetNodeWithLeastInstances()most probably returned the instances in a different order than usual. This led the scheduler to pick the node that is already hosting the instance as candidate.
