Individual Group Client's State is not being updated accordingly with the Parent Group State

Scenario:
1-create a group
2-disburse loan
3-check the individual state of the group clients (all have the account state=5 similar to the parent account)
4-close loan by applying a full payment
5-The parent account state is updated to 6, but the group client's states are equal to 5

expected result:
all group client accounts are updated accordingly to the parent group account

This behavior affects all group clients since they cannot be moved from one group to another

Workaround:
is to always update individual group accounts to be equal to the parent state
