scmutil: make shortesthexnodeidprefix() take a full binary nodeid

The shortest() template function depended on the behavior of
revlog._partialmatch() for these types of inputs:

  * non-hex strings
  * ambiguous strings
  * too long strings

revlog._partialmatch() seems to return the input unchanged in these
cases, but we shouldn't depend on such a low-level function to match
the behavior we want in the user-facing template function. Instead,
let's handle these cases in the template function and always pass a
binary nodeid to _partialmatch().
