This CL fixes bugs introduced when the premium list commands were moved to
be server-side commands.
Fixes:
- omitting the --name parameter actually works now; before it was failing
in the local build() call since it uses the name as the @Id and tries to
create a key for PremiumListRevision, but key IDs cannot be null.
- premium list data larger than about 2K works now (see [] before
it was stuffing the list data all into a POST query parameter, and URLs of
more than 2K in length were all getting 404s. Fix was changing it to put
the inputData param in the POST body.
- misc test cleanup
