Migrate one more feature renamed previously

The product feature was renamed along with the others for de-explorization of ansible
tower in: ManageIQ/manageiq#21108

The database migration in ManageIQ#564
handled most of the renames but one feature was missed.

This commit handles automation_manager_add_provider => ems_automation_add_provider.
