Speedup MessageDigestTests#testToHexString 

The purpose of this commit is to speed up the runtime of
MessageDigestTests#testToHexString. As written, the test contains a loop
that creates 1024 test cases leading to a test runtime on the order of a
few seconds. Given build infrastructure, a single test case should
suffice. Therefore, this commit removes this loop so that the test can
execute on the order of a couple hundred milliseconds.
