tag: do not pass binary nullid to scmutil.revsingle()

Future patches will remove the old-style parser that happen to accept a
binary nodeid. A binary nodeid shouldn't be passed to scmutil.revrange()
because it is ambiguous. For example, bin('20' * 19 + '30') is valid binary
nodeid, but it can also be parsed as a revset expression, '0'.
