test(tvix): Cover scanForReferences in a test r/1627
Aded a few test cases covering the scanForReferences function, which had been accidentally broken in 976a36c (which is now partially-reverted). As part of this, since the test needed to generate hashes for store paths, the logic in MakeStorePath to compress a sha256 hash down to 20 bytes and convert it to base32 has been extracted to a member function on the Hash class.
