Permissions rows get duplicated when upgrading from 4.0 to 4.1

[TheMasquerader]

When upgrading from UserFrosting 4.0.x to 4.1.x all the rows in the Permissions table get duplicated.
One current solution is to drop the Permissions table, remove the corresponding entry from the Migrations table, and re-run php bakery bake.

Note: other tables, e.g. roles, role_users, groups, permission_roles did not end up with duplicate rows after the 4.1 upgrade.
