FIX: Email Send post has already been taken error (#16992)
* FIX: Email Send post has already been taken error

Adding a failing test first before coming up with a good solution.

The above commit changed

```
PostReplyKey.find_or_create_by_safe!
```

to

```
PostReplyKey.create_or_find_by!
```

But I don't think it is working as a 1-1 replacement because of the
`Validation failed: Post has already been taken` error we are receiving
with this change. Also we need to make sure we don't re-introduce any
concurrency issues.

* Remove rails unique constraint and rely on db index

I believe this is what is causing `create_or_find_by!` to fail. Because
we have a unique constraint in the db I think we can remove this rails
unique constraint?

* clean up spec wording
