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

• #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
• #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)
