Provide a Replacement for hash "correct Tag" Test

[stenolog]

This test:

scrypto/shared/src/test/scala/scorex/crypto/hash/HashTest.scala

Lines 59 to 69 in 1d2db26

	property(s"${hash.getClass.getSimpleName} should return correct Tag") {
	forAll { (string: String, bytes: Array[Byte]) =>
	val digest = hash(string)
	digest.isInstanceOf[D] shouldBe true
	if (digest.isInstanceOf[Digest32]) {
	hash.DigestSize shouldBe 32
	} else if (digest.isInstanceOf[Digest64]) {
	hash.DigestSize shouldBe 64
	}
	}
	}

is not functional within scala 2.

This came up during work on

• Scala3 support #108

Reproduce

• just replace 32/64 hash.DigestSize shouldBe 32 with a wrong value, the test will not fail.
• or: add breakpoints to lines 64 and 66
• or: add else { fail("Tag is not Digest32 or Digest64") } to line 67
• Scala3 support #108 (review) (reproducer in CI)

Tasks

• disable the non-functioning part
• find a solution to have the Tag available in runtime
• provide a new test (for scala 2 and 3)
