reserveThenGetNamePaths import combines bundles

[dckc]

We changed one line in start-kread-proposal.js and 3 of the 4 bundles changed.

This import seems awkward:

KREAd/agoric/contract/src/proposal/kread-committee-proposal.js

Line 3 in 875f5de

import { reserveThenGetNamePaths } from './start-kread-proposal.js';

suggestion: move the two reserveThen... to a new module/file.
