The test "updates officer_assignment_id_log if amount changes" failed
when the ID we assigned when creating the records was the same as the ID
of the first officer assignment created during that test. It's recently
happened while running our test suite [1] with the following error:
```
1) Poll::Recount logging changes updates officer_assignment_id_log if
amount changes
Failure/Error: poll_recount.officer_assignment =
create(:poll_officer_assignment, id: 101)
ActiveRecord::RecordNotUnique:
PG::UniqueViolation: ERROR: duplicate key value violates unique
constraint "poll_officer_assignments_pkey"
DETAIL: Key (id)=(101) already exists.
```
We're also removing the IDs in the "updates officer_assignment_id_log if
amount changes" test to avoid any possible issues, even if in this test
I think no other officer assignments are created and so there can't be
another record with the same ID.

This test will fail if the ID of the created record is the same as the ID of the first user we create in the test. The chance is very low due to the `rand(9999999)` which causes the test to fail just once every ten million times. However, why assigning the ID in the first place? Without it, the test will never fail due to conflicting IDs.
