state/apiserver: add test for ignored rpc methods

With the rpcreflect package in place, we can make
a test that makes sure that RPC methods are not ignored
without good cause.

We could also potentially add a test that the set of exported
RPC methods is exactly what is expected, which might
actually be useful to make sure that we are not accidentally
exporting unintended functionality.

LGTM provided the earlier patch lands.

I'm ok with a blacklist, but we might just want a whitelist test. (both?) and
then when you add something you update the lists.
