Using references wrong does not generate error

[jeroen11dijk]

Describe the bug
I had a matching table resource with a has_many to timeslots, and wanted to delete those if the matching table got remove. So I added the following to matching table:

references do
  reference :timeslots, on_delete: :delete
end

Turns out you need to do it on the belongs_to but this didnt give any warnings when generating migrations just that there werent any changes. I dont know if its possible to add a warning but would imo be a nice change

To Reproduce
Create two resources, one with a has_many and the other with a belongs_to. Then add a delete reference to the one with the has_many relationship and try to generate migrations.

Expected behavior
I would expect either an error or warning saying that this reference is useless and a suggestion to put it on the belongs_to resource.
