CLEANUP: resolvers/cli: remove the unneeded appctx->st2 from "show resolvers"

Browse Source 
The command uses this state but _INIT immediately turns to _LIST, which
turns to _FIN at the end without doing anything in that state, thus the
only existing state is _LIST so we don't need to store a state. Let's
just get rid of it.
