Make tests more terse + fix typing on UniqueOpts (#13)

I'm getting to a place soon where I'm going to have to add a new set of
tests for asynchronous operations, so in preparation for that, here we
go through and make the tests more terse in a few ways:

* Remove time mocks for tests they're not needed (most of them).

* Remove local variables that aren't needed (instead just use the value
  directly). i.e. `args` can just be `JobArgs()` values, `UniqueOpts`
  can just go right onto `InsertOpts`.

* Replace the name `result` with the more specific `insert_res`
  (suggesting it's a result for an insert rather than an arbitrary
  result).

Also found a bad value for `by_args` in one test and realized that it
wasn't being detected because the fields on `UniqueOpts` didn't have
type annotations on them. Add type annotations to make this impossible
in the future.
