This is a defensive test, just in case we decide to go back to using
`setseed` instead of the `modulus`[1] approach to display investments
in random order
The reason for this test is that `setseed` only ~works in the next
`select` statement. And as when loading a user’s votes for investments
we do a second `select` it does not work as expected 😌
To solve this… we could call `set_random_seed` before loading a user’s
votes for an investment[2]
