Use proposal ballots for voting state

[mstrasinskis]

Motivation

There are multiple reports from users who can’t vote. We believe the root cause of this issue is the 100-ballot limit for neurons. If a user has voted on more than 100 proposals (a likely scenario over a 4-day period), they don’t receive ballots for proposals they’ve already voted on, which remain technically votable due to this limit. The suggested solution is to switch from using neuron ballots to proposal ballots when calculating the votable state.

The utilities have already been already updated in ic-js - dfinity/ic-js#725

Changes

• npm run upgrade:next
• Update the displayed votable neurons on proposal changes as well, since we use the proposal ballots to determine the neurons’ voting state.

Tests

• Updated.
• Manually

1. Created 100+ proposals.
2. Voted on them.
3. Ensured that some of them were still displayed as votable (due to the recentBallots limit).
4. Switched to the utilities that rely on the proposal ballots.
5. Verified that all the proposals previously displayed as votable (despite having already been voted on) were now displayed as voted.

Todos

• Add entry to changelog (if necessary).
