fix(authz): [FC-0099] invalidate PermissionsByRole to update number of user in a role

[dcoa]

Description

Currently the counter of users by role is not being updated when an add/delete role is executed. This is because we are not invalidating the PermissionsByRole query that is where this value comes from.
