phases: stop using `repo.set` in `remotephasessummary`
The `repository.set` create changectx on the fly, an expensive operation. Using
`repo.revs` and a direct rev-num → node-id translation will be significantly
faster.
This is especially true as we prepare ourself to no longer do the rev-num →
node-id transalation there.
The speedup is a bit lost in the overall noisyness of the slow phase discovery algorithm, but it save a small amount of time in my benchmark.
