Carl Dong 6be7d14d24 Properly generate salt in rpcauth.py, update tests
Previously, when iterating over bytes of the generated salt to construct
a hex string, only one character would be outputted when the byte is
less than 0x10. Meaning that for a 16 byte salt, the hex string might be
less than 32 characters and collisions would occur.
