Comment 2 for bug 1995527

To test this you would need to have a site installed before the submissions plugin existed

1) Install Mahara 20.04_STABLE
2) Upgrade to main
3) Check the extenstions -> plugins page the 'module' submissions should NOT be installed
4) Create a group
5) Delete the group

Expected result:

The group is deleted

Actual result:

There is an SQL error and the group doesn't delete
