Postgressuite and ItemsRoute intermittent failures

[gitplaneta]

If you change shop.generators.nonEmptyStringGen to generate shorter strings, ex. to:

  val nonEmptyStringGen: Gen[String] =
    Gen
      .chooseNum(1, 40)
      .flatMap { n =>
        Gen.buildableOfN[String, Char](n, Gen.alphaChar)
      }

PostgresSuite will more likely fail with unique constraint violations and ItemsRuiteSuite:items by brand succeeds will fail because of toLowerCase.capitalize in BrandParam.toDomain string manipulation.
