Steps to reproduce

1. Create a migration
2. Use create_table to add a table called :users like this:

create_table :users, force: true do |t|
end

3. Use create_table to add a table called :posts that references :users like this:

create_table :posts, force: true do |t|
  t.references :users, nnull: false, uniqe: true 
end

**** NOTE that 'nnull' and 'uniqe' are non-existent options!! ****

4. Run the migration

I created a runnable gist to illustrate the issue here: https://gist.github.com/georgewambold/16ee14cb0e5ca77b35ff3c94b4537475

Expected behavior

An error should be raised

Actual behavior

The migration changes are commited without raising an error

System configuration

Rails version: 6.0.0.alpha

Ruby version: 2.5.1

This is my first issue and I'd love to write the fix if the issue is accepted.

This issue is similar to issue 8104 and PR 32675
