referential_lock_during_creation_spec: Make truncation strategy stick

The `truncation: true` strategy wasn't sticking. The config `before`
block only ran once for this test file. Instead of attaching the filter
to the `it` blocks, put it on the `context`. This correctly gets each
test to run in a transaction.

Remove the `truncation: false` filter I had added previously as this
didn't do what I wanted it to: it prevented the `before` block from
running instead of filtering out tests with `truncation: true`.
