Calc should probably offer "si" as the default in this case.

Calc shouldn't offer "1" as a default; I'll fix it so that it doesn't
do that anymore.
I'll also change it so that Calc can offer unit systems and composite
units as default units, but that should probably wait until after 24.1
comes out.
