queryset-refactor: Fixed up extra(select=...) calls with parameters so that the

parameters are substituted in correctly in all cases. This introduces an extra
argument to extra() for this purpose; no alternative there.

Also fixed values() to work if you don't specify *all* the extra select aliases
in the values() call.

Refs #3141.
